UC3842B/3843B
LINEAR INTEGRATED CIRCUIT
HIGH PERFORMANCE CURRENT MODE CONTROLLERS
DESCRIPTION
The UTC UC3842B/3843B are specifically designed for off-line and dc-to-dc converter applications offering the designer a cost-effective solution with minimal external components.
The UC3842B has UVLO thresholds 16V (on) and 10V(off), ideally suited for off-line converters. The UC3843B is tailored for lower voltage applications having UVLO thresholds of 8.4V(on) and 7.6V(off).
