We need Voltage mode PWM controller with dual FET driver and minimum switching frequency about 25KHz
for our push pull DC-DC converter application.
PWM controller should have additional features as given below,
1. External frequency synchronization
2. Programmable dead time adjustability, Softstart and shutdown
3. programmable UVLO hysterises
Kindly do the needful to let us know about availability of PWM controller IC with above expected features and its application note.
We can offer our SG3525A pulse width modulator control circuit. The SG3525A pulse width modulator control circuit offers improved performance and lower external parts count when implemented for controlling all types of switching power supplies.
