Description
The QBVS050A0B Barracuda series of dc-dc converters are a new generation of fully regulated DC/DC power modules designed to support 12.0Vdc intermediate bus applications where multiple low voltages are subsequently generated using point of load (POL) converters, as well as other application requiring a tightly regulated output voltage. The QBVS050A0B series operate from an input voltage range of 52 to 60Vdc and provide up to 50.0A output current at output voltages of 12.0V compliant quarter brick. The converter incorporates digital control, synchronous rectification technology, a fully regulated control topology, and innovative packaging techniques to achieve efficiency exceeding 97% at 12.0V output. This leads to lower power dissipations such that for many applications a heat sink is not required. Standard features include on/off control, output overcurrent and over voltage protection, over temperature protection, input under and over voltage lockout.
The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for both input and output minimizes the need for external filtering.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 25A in the ungrounded input lead of the power supply (see Safety Considerations section). Based on the information provided in this Data Sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s Data Sheet for further information.

Design Considerations
Input Source Impedance
The power module should be connected to a low ac-impedance source. Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 9, a 680μF electrolytic capacitor, C (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit.
Safety Considerations
For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950-1 2 VDE0805-1 EN60950-1 2
nd
Ed., CSA C22.2 No. 60950-1 2nd Ed., and
nd
Ed.
If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75Vdc), for the module’s output to be considered as meeting the requirements for safety extra-low voltage (SELV), all of the following must be true:
The input source is to be provided with reinforced
insulation from any other hazardous voltages, including the ac mains.
One V
pin and one V
IN
OUT
both the input and output pins are to be kept floating.
The input pins of the module are not operator
accessible.
Another SELV reliability test is conducted on the whole
system (combination of supply source and subject module), as required by the safety agencies, to verify that under a single fault, hazardous voltages do not appear at the module’s output.
Note: Do not ground either of the input pins of the module
without grounding one of the output pins. This may allow a non-SELV voltage to appear between the output pins and ground.
The power module has safety extra-low voltage (SELV) outputs when all inputs are SELV.
The input to these units is to be provided with a maximum 25A fast-acting (or time-delay) fuse in the ungrounded input lead.

Feature Descriptions
Overcurrent Protection
To provide protection in a fault output overload condition, the module is equipped with internal current-limiting circuitry and can endure current limiting continuously. If the overcurrent condition causes the output voltage to fall greater than 3.0V from V remain latched off. The overcurrent latch is reset by either cycling the input power or by toggling the on/off pin for one second. If the output overload condition still exists when the module restarts, it will shut down again. This operation will continue indefinitely until the overcurrent condition is corrected.
A factory configured auto-restart option (with overcurrent and overvoltage auto-restart managed as a group) is also available. An auto-restart feature continually attempts to restore the operation until fault condition is cleared.
Remote On/Off
The module contains a standard on/off control circuit reference to the V remote on/off logic options are available. Positive logic remote on/off turns the module on during a logic-high voltage on the ON/OFF pin, and off during a logic low. Negative logic remote on/off turns the module off during a logic high, and on during a logic low. Negative logic, device code suffix "1," is the factory-preferred configuration. The On/Off circuit is powered from an internal bias supply, derived from the input voltage terminals. To turn the power module on and off, the user must supply a switch to control the voltage between the On/Off terminal and the V terminal (V equivalent (see Figure 12). A logic low is V The typical I Terminal=0.3V) is 147µA. The switch should maintain a logic­low voltage while sinking 200µA. During a logic high, the maximum V maximum allowable leakage current of the switch at V
2.4V is 130µA. If using an external voltage source, the maximum voltage V

Output Overvoltage Protection
The module contains circuitry to detect and respond to output overvoltage conditions. If the overvoltage condition causes the output voltage to rise above the limit in the Specifications Table, the module will shut down and remain latched off. The overvoltage latch is reset by either cycling the input power, or by toggling the on/off pin for one second. If the output overvoltage condition still exists when the module restarts, it will shut down again. This operation will continue indefinitely until the overvoltage condition is corrected.
A factory configured auto-restart option (with overcurrent and overvoltage auto-restart managed as a group) is also available. An auto-restart feature continually attempts to restore the operation until fault condition is cleared.
Overtemperature Protection
These modules feature an overtemperature protection circuit to safeguard against thermal damage. The circuit shuts down the module when the maximum device reference temperature is exceeded. The module will automatically restart once the reference temperature cools by ~25°C.
Input Under/Over voltage Lockout
At input voltages above or below the input under/over voltage lockout limits, module operation is disabled. The module will begin to operate when the input voltage level changes to within the under and overvoltage lockout limits.
Thermal Considerations
The power modules operate in a variety of thermal environments and sufficient cooling should be provided to help ensure reliable operation. Thermal considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. Heat-dissipating components are mounted on the top side of the module. Heat is removed by conduction, convection and radiation to the surrounding environment. Proper cooling can be verified by measuring the thermal reference temperature (TH1).
Peak temperature occurs at the position indicated in Figure
16. For reliable operation this temperature should not exceed TH limit this temperature to a lower value. The output power of the module should not exceed the rated power for the module as listed in the Ordering Information table.

Heat Transfer via Convection
The thermal data presented here is based on physical measurements taken in a wind tunnel, using automated thermo-couple instrumentation to monitor key component temperatures: FETs, diodes, control ICs, magnetic cores, ceramic capacitors, opto-isolators, and module pwb conductors, while controlling the ambient airflow rate and temperature. For a given airflow and ambient temperature, the module output power is increased, until one (or more) of the components reaches its maximum derated operating temperature, as defined in IPC-9592A. This procedure is then repeated for a different airflow or ambient temperature until a family of module output derating curves is obtained. Please refer to the Application Note “Thermal Characterization Process For Open-Frame Board-Mounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures.

24.
Layout Considerations
The QBVS050A0B power module series are low profile in order to be used in fine pitch system card architectures. As such, component clearance between the bottom of the power module and the mounting board is limited. Avoid placing copper areas on the outer layer directly underneath the power module. Also avoid placing via interconnects underneath the power module.
For additional layout guide-lines, refer to FLT012A0Z Data Sheet.
Through-Hole Lead-Free Soldering Information
The RoHS-compliant, Z version, through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. The module is designed to be processed through single or dual wave soldering machines. The pins have a RoHS-compliant, pure tin finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max.
Reflow Lead-Free Soldering Information
The RoHS-compliant through-hole products can be processed with the following paste-through-hole Pb or Pb­free reflow process.
Max. sustain temperature : 245C (J-STD-020C Table 4-2: Packaging Thickness>=2.5 / Volume > 2000 Peak temperature over 245C is not suggested due to the potential reliability risk of components under continuous high-temperature.

MSL Rating
The QBVS050A0B modules have a MSL rating of 2a.
Storage and Handling
The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of 30°C and 60% relative humidity varies according to the MSL rating (see J-STD-060A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40° C, < 90% relative humidity.

Post Solder Cleaning and Drying Considerations
Post solder cleaning is usually the final circuit board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to Lineage Power Board Mounted Power Modules: Soldering and Cleaning Application Note (AN04-001).
