UC3842BN ШИМ-контроллер (DIP-8) купить в Краснодаре

The UC384xB family of control ICs provides the nec￾essary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally imple￾mented circuits include a trimmed oscillator for pre￾cise DUTY CYCLE CONTROL under voltage lock￾out featuring start-up current less than 0.5mA, a pre￾cision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control, and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N-Channel MOSFETs, is low in the off￾state
