UC3526AN Description

Short technical summary and product information.

The Texas Instruments UC3526AN is a pulse-width modulator (PWM) controller IC designed for DC/DC switching regulator applications. It supports multiple topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations.

 

Key electrical specifications include an operating voltage range of 7V to 35V and an adjustable oscillator frequency from 1Hz up to 600kHz. The maximum duty cycle is rated at 49%. Control features include Enable, Frequency Control, Reset, and Soft Start, providing flexibility in power supply design.

 

This component is housed in an 18-PDIP package and is designed for through-hole mounting. The operating temperature range is from 0°C to 70°C (TA). The UC3526AN is noted as not recommended for new designs, with alternatives like the TL494 available.

 

It features dual 200mA source/sink outputs, minimum output cross-conduction, double-pulse suppression logic, under-voltage lockout, and thermal shutdown protection. The device also includes TTL/CMOS compatible logic ports and operates at 5 Volt (VIN = VC = VREF = 5.0V).
