Produktoversikt

The UCC3804DG4 is a low-power BiCMOS current-mode Pulse Width Modulation (PWM) Controller contains all of the control and drive components required for off-line and DC to DC fixed frequency current-mode switching power supplies with minimal parts count. It offers the added features of internal full-cycle soft start and internal leading-edge blanking of the current-sense input. It contains digital current sense filtering, which disconnects the CS terminal from the current sense comparator during the 100ns interval immediately following the rising edge of the OUT pin. This digital filtering, also called leading-edge blanking, means that in most applications, no analog filtering (RC filter) is required on CS. Compared to an external RC filter technique, the leading-edge blanking provides a smaller effective CS to OUT propagation delay.
  • Internal soft start
  • Internal fault soft start
  • Internal leading-edge blanking of the current sense signal
  • 70ns Typical response from current-sense to gate-drive output
  • 1.5% Tolerance voltage reference
  • Green product and no Sb/Br
