The UC3842B/3B/4B/5B, series are high performance fixed frequency current mode controllers.

Line and dc to dc converter applications offering the designer a cost effective solution wi

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. These devices are available in an 8.
pin dual.
in.
line and surface mount (SO.
8) plastic package as well as the 14.
pin plastic surface mount (SO.
14). The SO.
14 package has separate power and ground pins for the totem pole output stage. The UCX842B has.
