UC3524AN General Description

The UC3524AN is a high-performance PWM controller IC designed for power supply and power management applications. It features a 5V reference voltage with a ±1% accuracy, making it suitable for precision voltage regulation. The device can operate at a wide input voltage range from 8V to 40V, making it versatile for various power supply designs.The UC3524AN offers a flexible operating frequency up to 500kHz, allowing for high-efficiency power conversion. It has built-in protection features such as overcurrent protection and thermal shutdown to ensure the safe operation of the power supply.This PWM controller also features a voltage feedforward compensation function that improves the load regulation of the power supply. It has a temperature range of -40°C to 85°C, making it suitable for a wide range of operating environments.

Key Features

The UC3524AN is a voltage mode pulse width modulator IC with features such as adjustable frequency, duty cycle, soft-start, and external synchronization

It also has overcurrent and overvoltage protection, a precision reference voltage, and a high-speed error amplifier

Application
