The UCC3813D-0 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 has the same pin configuration as the UC384x family and also offers the added features of internal full-cycle soft start and internal leading-edge blanking of the current-sense input.
● Internal soft start
● Internal fault soft start
● Internal leading-edge blanking of the current-sense signal
● 1A Totem-pole output
● 70ns Typical response from current-sense to gate-drive output
● 1.5% Tolerance voltage reference
● Green product and no Sb/Br
