UC3842 General Description

Another key highlight of the UC3842 is its comprehensive internal circuits, including logic for latched operation, a PWM comparator for current-limit control, and a totem-pole output stage capable of handling high-peak currents. This output stage is specifically designed for driving N-channel MOSFETs and maintains a low state when off, contributing to energy efficiency in the system. With various package options, temperature ranges, and threshold choices, the UC3842 family caters to a wide range of application needs
