The UCC3804DTR is a pulse width modulation (PWM) controller

Product overview

The UCC3804DTR is a low power BiCMOS current mode pulse width modulation (PWM) controller that contains all necessary drive and control components for DC and offline fixed frequency current mode switching power supplies. to CC with minimal piece count. It offers the additional features of internal full cycle soft start and state-of-the-art internal suppression of the current sense input. It contains current sense digital filtering, which turns off the CS terminal of the current sense comparator during the 100ns interval immediately after the rising edge of the OUT pin.

It offers the additional features of internal full cycle soft start and state-of-the-art internal suppression of the current sense input. It contains current sense digital filtering, which turns off the CS terminal of the current sense comparator during the 100ns interval immediately after the rising edge of the OUT pin. This digital filtering, also called cutting edge blanking, means that in most applications, no analog filtering (RC filter) is required in CS. Compared to an external RC filter technique, state-of-the-art suppression provides a smaller effective CS to OUT propagation delay.
