capacitor from VDD to GND. The worse case current from this source should be less thanthe current needed to run the device in normal operation. The capacitor is needed to provide the reservoir of energy to allow the completion of the startup process before the UVLO voltage is encountered. Once started the converter should be designed so that it is self powered from a controlled voltage source of a lower voltage, one between 9.5 V and 11.5 V. The device is not designed to have the VDD clamp active during normal operation. The VDD voltage is always less than the clamp voltage.

PIN DESCRIPTIONS

COMP: COMP is the output of the error amplifier and the input of the PWM comparator. The error amplifier in
the UCC3807 is a low output impedance, 2 MHz operational amplifier. COMP can both source and sink current. The error amplifier is internally current limited, which allows zero duty cycle by externally forcing COMP to GND.
The UCC3807 family features built-in full cycle soft start. Soft start is implemented as a clamp on the maximum COMP voltage.
CS: Current sense input. There are two current sense comparators on the chip, the PWM comparator and an overcurrent comparator.
The UCC3807 also contains a leading edge blanking circuit, which disconnects the external CS signal from the current sense comparator during the 100 ns interval immediately following the rising edge of the signal at the OUT pin. In most applications, no analog filtering is required on CS. Compared to an external RC filtering technique, leading edge blanking provides a smaller effective CS to OUT propagation delay. Note, however, that the minimum non-zero on-time of the OUT signal is directly affected by the leading edge blanking and the CS to OUT propagation delay.
The overcurrent comparator is only intended for fault sensing. Exceeding the overcurrent threshold causes a soft start cycle.
FB: The inverting input to the error amplifier. For best stability, keep connections to FB as short as possible and stray capacitance as small as possible.
GND: Reference ground and power ground for all functions of the part. OUT: The output of a high current power driver capable of driving the gate of a power MOSFET with peak
currents exceeding 1A. OUT is actively held low when VDD is below the UVLO threshold. The high current power driver consists of MOSFET output devices in a totem pole configuration. This allows the
output to switch from VDD to GND. The output stage also provides a very low impedance which minimizes overshoot and undershoot. In most cases, external Schottky clamp diodes are not required.
TRIG/DISCH: Oscillator control pins. Trig is the oscillator timing input, which has an RC-type charge/discharge signal controlling the chip’s internal oscillator. DISCH is the pin which provides the low impedance discharge path for the external RC network during normal operation. Oscillator frequency and maximum duty cycle are computed as follows:
as shown in Figure 1 . For best performance, keep the lead from C
is desirable. The minimum value of R C
is 47 pF.
T
A
to GND as short as possible. A separate ground connection for C
T
is 10 k , the minimum value of R
is 2.2 k , and the minimum value of
B
VDD: The power input connection for this device. Total VDD current is the sum of quiescent current and the average OUT current. Knowing the operating frequency and the MOSFET gate charge (Qg), average OUT current can be calculated from
I
= Qg F, where F is frequency.
OUT
To prevent noise problems, bypass VDD to GND with a ceramic capacitor as close to the chip as possible in parallel with an electrolytic capacitor. Once started and operating properly the V
voltage should be below the
DD
clamp voltage of the device.

APPLICATION INFORMATION

The circuit shown in Figure 2 illustrates the use of the UCC3807 in a typical off-line application. The 100-W, 200-kHz, universal input forward converter produces a regulated 12VDC at 8 Amps. The programmable maximum duty cycle of the UCC3807 allows operation down to 80VRMS and up to 265VRMS with a simple RCD clamp to limit the MOSFET voltage and provide core reset. In this application the maximum duty cycle is set to about 65%. Another feature of the design is the use of a flyback winding on the output filter choke for both bootstrapping and voltage regulation. This method of loop closure eliminates the optocoupler and secondary side regulator, common to most off-line designs, while providing good line and load regulation.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
