DESCRIPTION

HPC1094C, uPC1094G are PWM type switching regulator control circuit up to 500 kHz switching frequency. These devices feature low standby current, totem pole output circuit which can directly drive the gate of power MOS FET at high speed, and various protection circuits. These devices are optimum choise for the single ended primary control method switching regulator.

FEATURES

© Directly switching the gate of an external power MOS FET at high speed. (Ic(peak) = 1.2 A) @ Low supply current. @ Internal low voltage stop circuit. @ Internal ON/OFF control circuit. @ Over current sense pin appendant. © Capable of master slave operation.
