- Part of the PJ3842B_Promax comparator family.
PJ3842B / PJ3843B High Performance Current Mode Controller he PJ3842B and PJ3843B series are high performance fixed frequency current mode controllers. This is 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. The PJ3843B is tailored for lowervoltage applications having UVLO thresholds of 8.5V (on) and 7.6V (off). specifically designed for...
