Add To BomUC3845D General Description
The UC3845D is a pulse width modulation (PWM) controller IC designed for power supply applications. It operates at a fixed frequency and can be used in both isolated and non-isolated power supplies. The UC3845D features a voltage reference, error amplifier, oscillator, PWM comparator, dead-time control, and high current totem pole outputs.This device provides precise control of the output voltage by adjusting the duty cycle of the PWM signal. It offers adjustable soft-start and current limit functions for protection against overcurrent conditions. The UC3845D also has an undervoltage lockout feature to ensure safe operation during startup.With a wide input voltage range and high output current capacity, the UC3845D is suitable for various power supply designs. It is commonly used in switch-mode power supplies, lighting applications, battery chargers, and DC-DC converters. The IC comes in a dual in-line package (DIP) or surface-mount package for easy integration into circuit boards.
