The thermal curves provided are based upon measurements made in TDK Innoveta’s experimental test setup that is described in the Thermal Management section. Due to the large number of variables in system design, TDK Innoveta recommends that the user verify the module’s thermal performance in the end application. The critical component should be thermo- coupled and monitored, and should not exceed the temperature limit specified in the derating curve above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact otherwise significant measurement errors may result.

Thermal Management:

An important part of the overall system design process is thermal management; thermal design must be considered at all levels to ensure good reliability and lifetime of the final system. Superior thermal design and the ability to operate in severe application environments are key elements of a robust, reliable power module.

A finite amount of heat must be dissipated from the power module to the surrounding environment. This heat is transferred by the three modes of heat transfer: convection, conduction and radiation. While all three modes of heat transfer are present in every application, convection is the dominant mode of heat transfer in most applications. However, to ensure adequate cooling and proper operation, all three modes should be considered in a final system configuration.

The open frame design of the power module provides an air path to individual components. This air path improves convection cooling to the surrounding environment, which reduces areas of heat concentration and resulting hot spots.

Test Setup: The thermal performance data of the power module is based upon measurements obtained from a wind tunnel test with the setup shown in the wind tunnel figure. This thermal test setup replicates the typical thermal environments encountered in most modern electronic systems with distributed power architectures. The

The cross section of the airflow passage is rectangular with the spacing between the top of the module and a parallel facing PCB kept at a constant (0.5 in). The power module’s orientation with respect to the airflow direction can have a significant impact on the unit’s thermal performance.

Thermal Derating: For proper application of the power module in a given thermal environment, output current derating curves are provided as a design guideline in the

vertically mounted printed circuit boards (PCBs) or circuit cards in cabinet racks.

The power module is mounted on a 0.062 inch thick, 6-layer, 2oz/layer PCB and is vertically oriented within the wind tunnel. Power is routed on the internal layers of the PCB. The outer copper layers are thermally decoupled from the converter to better simulate the customer’s application. This also results in a more conservative derating.

performance page for the power module of interest. In all conditions, the power module should be operated below the maximum operating temperature shown on the derating curve. For improved design margins and enhanced system reliability, the power module may be operated at temperatures below the maximum rated operating temperature.

Heat transfer by convection can be enhanced by increasing the airflow rate that the power module experiences. The maximum output current of the power module is a function of ambient temperature (T

) and airflow rate as shown in the

AMB

thermal performance figures on the thermal performance page for the power module of interest. The curves in the figures are shown for natural convection through 3 m/s (600 ft/min). The data for the natural convection condition has been collected at

0.3 m/s (60 ft/min) of airflow, which is the typical airflow generated by other heat dissipating components in many of the systems that these types of modules are used in. In the final system configurations, the airflow rate for the natural convection condition can vary due to temperature gradients from other heat dissipating components.

Heatsink Usage: For applications with demanding environmental requirements, such as higher ambient temperatures or higher power dissipation, the thermal performance of the power module can be improved by attaching a heatsink or cold plate. The iQP platform is designed with a base plate with two M3 X 0.5 throughthreaded mounting fillings for attaching a heatsink or cold plate. The addition of a heatsink can reduce the airflow requirement; ensure consistent operation and extended reliability of the system. With improved thermal performance, more power can be delivered at a given environmental condition.

Standard heatsink kits are available from TDK Innoveta Inc. for vertical module mounting in two different orientations

(longitudinal – perpendicular to the direction of the pins and transverse – parallel to the direction of the pins). The heatsink kit contains four M3 x 0.5 steel mounting screws and a precut thermal interface pad for improved thermal resistance between the power module and the heatsink. The screws should be installed using a torquelimiting driver set between 0.35-0.55 Nm (35 in-lbs).

The system designer must use an accurate estimate or actual measure of the internal airflow rate and temperature when doing the heatsink thermal analysis. For each application, a review of the heatsink fin orientation should be completed to verify proper fin alignment with airflow direction to maximize the heatsink effectiveness. For TDK Innoveta standard heatsinks, contact TDK Innoveta Inc. for latest performance data.

Operating Information:

Over-Current Protection: The power

modules have current limit protection to protect the module during output overload and short circuit conditions. During overload conditions, the power modules may protect themselves by entering a hiccup current limit mode. The modules will operate normally once the output current returns to the specified operating range. There is a roughly 2ms delay from the time an overload condition appears at the module output until the hiccup mode will occur. A latched overcurrent protection option is also available. Consult the TDK Innoveta technical support for details.

Output Over-Voltage Protection: The power modules have a control circuit, independent of the main control loop, that reduces the risk of over voltage appearing at the output of the power module during a fault condition. If there is a fault in the main regulation loop, the over voltage protection circuitry will latch the power module off once it detects the output voltage condition as specified on the Electrical Data page. To remove the module from the latched condition, either cycle the input power or toggle the remote ON/OFF pin providing that over-voltage conditions have been removed. The reset time of the ON/OFF pin should be 500ms or longer.

The iQP Powereta family also offers an optional feature to allow non-latching 1second hiccup mode over-voltage protection. Consult the TDK Innoveta technical support for details.

Thermal Protection: When the power modules exceed the maximum operating temperature, the modules will turn-off to safeguard the units against thermal damage. The module will auto restart as the unit is cooled below the over temperature threshold. A latched over-temperature protection option is also available. Consult the TDK Innoveta technical support for details.

Remote On/Off: - The power modules have an internal remote on/off circuit. The user must supply an open-collector or compatible switch between the Vin(-) pin and the on/off pin. The maximum voltage generated by the power module at the on/off terminal is 15V. The maximum allowable leakage current of the switch is 50uA. The switch must be capable of maintaining a low signal Von/off < 1.2V while sinking 1mA.

The standard on/off logic is negative logic. The module will turn on if pin 2 is connected to pin 3, and it will be off if pin 2 is left open. If the negative logic feature is not being used, pin 2 should be shorted to pin 3.

An optional positive logic is available. The power module will turn on if pin 2 is left open and will be off if pin 2 is connected to pin 3. If the positive logic circuit is not being used, terminal 2 should be left open.

Output Voltage Adjustment: The output

voltage of the module may be adjusted by using an external resistor connected between the trim pin 6 and either the Sense (+) or Sense (-) pin. If the voltage trim feature is not used, pin 6 should be left open. Care should be taken to avoid injecting noise into the module’s trim pin. A small 0.01uF capacitor between the power module’s trim pin and Sense (-) pin may help to avoid this.

With a resistor between the trim pin and Sense (-) pin, the output voltage is adjusted down. To adjust the output voltage down a percentage of Vout (∆%) from Vo,nom, the trim resistor should be chosen according to the following equation:

The value of Vref can be found in the Electrical Data section of this data sheet. The maximum power available from the power module is fixed. As the output voltage is trimmed up, the maximum output current must be decreased to maintain the maximum rated power of the module. It is also desirable to slightly increase the input voltage while trimming up the output with heavy load current.

As the output voltage is trimmed up, the output over-voltage protection set point is not adjusted. Trimming the output voltage too high may cause the output over voltage protection circuit to be triggered.

The capacitor C1 across the input shall be at least one 220µF/100V electrolytic capacitor along with two 1uF to 2.2uF/100V ceramic capacitors. Two 220µF/100V electrolytic capacitors and two 2.2uF/100V ceramic capacitors are recommended. A 220µF/100V capacitor for C0 is also recommended.

The output ripple measurement is made approximately 7 cm (2.75 in.) from the power module using an oscilloscope and BNC socket. The capacitor Cext is located about 5 cm (2 in.) from the power module; its value varies from code to code and is found on the electrical data page for the power module of interest under the ripple & noise voltage specification in the Notes & Conditions column.

Safety Considerations:

For safety agency approval of the system in which the DC-DC power module is installed, the power module must be installed in compliance with the creepage and clearance requirements of the safety agency. The isolation is basic insulation. For applications requiring basic insulation, care must be taken to maintain minimum creepage and clearance distances when routing traces near the power module.

As part of the production process, the power modules are hi-pot tested from primary and secondary at a test voltage of 1500Vdc.

To preserve maximum flexibility, the power modules are not internally fused. An external input line normal blow fuse with a maximum value of 15A is required by safety agencies. A lower value fuse can be selected based upon the maximum dc input current and maximum inrush energy of the power module.

When the supply to the DC-DC converter is less than 60Vdc, the power module meets all of the requirements for SELV. If the input voltage is a hazardous voltage that exceeds 60Vdc, the output can be considered SELV only if the following conditions are met:

1) The input source is isolated from the ac mains by reinforced insulation.

2) The input terminal pins are not accessible.

3) One pole of the input and one pole of the output are grounded or both are kept floating.

4) Single fault testing is performed on the end system to ensure that under a single fault, hazardous voltages do not appear at the module output.
