he PJ3842B series is high performance fixed frequency
current mode controllers. This is specifically designed
for Off-Line and DC-to-DC converter applications offering
the designer a cost effective solution with minimal external
components.This integrated circuits feature a trimmed
oscillator for precise duty cycle control, a temperature
compensated reference, high gain error amplifier, current
sensing comparator,and a high current totem pole output
ideally suited for driving a power MOSFET.
Also included are protective 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.
