Overview

HOTCHIP UC3842/43(B) High Performance Current Mode Controller Description The UC3842B/43B series are high performance fixed frequency current mode controllers.
They are specifically designed for Off-Line and DC-to-DC converter applications offering the designer a cost effective solution with minimal external components.
These 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 under voltage lockouts each with hysteresis, ...
