UCC2803D

ШИМ контроллер токового режима, 12В-3.6В питание, 1МГц, 4.06В/1A выход, SOIC-8.

The UCC2803D 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 has the same pin configuration as the UC2842/3/4/5 family and also offers the added features of internal full-cycle soft start and internal leading-edge blanking of the current-sense input. It offers choice of maximum duty cycle and critical voltage levels.
