PJ3842B
features consisting of input and reference undervoltage lockouts each with hysteresis, cycle-by-cycle current limiting , programmable output deadtime, and a latch for single pulse metering. This device is available in 8-pin dual-in-line plastic packages as well as the 8-pin plastic surface mount (SOP-8). The SOP-8 package has separate power and ground pins for the totem pole output stage. The PJ3842B has UVLO thresholds of 16V (on) and 10V (off), ideally suited for off-line converters. for Off-Line and DC-to-DC convert er applications offering the designer a cost effective solution with minimal external ponents.This integrated circuits feature a trimmed oscillator for precis e duty cycle control, a temperature pensated reference, high gain error amplifier, current sensing parator,and a high current totem pole output ideally suited for driving a power MOSFET.
