UCC2804D, ШИМ контроллер связь по току BiКМОП

Описание UCC2804D The UCC2804D 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. • 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 Тип преобразователяboost, flyback, forwardНаличие изоляции выходанетНаличие внутреннего коммутатораестьМаксимальная частота преобразователя, кГц1000Максимальная скважность преобразователя, %49Защита от сбоевcur.lim.Особенности управленияfrequency controlРабочая температура,°С-40…+85Корпусsoic-8(0.154 inch)Вес, г0.3
