UC3526ADW Description

Short technical summary and product information.

The UC3526ADW from Texas Instruments is a pulse-width modulator (PWM) controller IC. It is designed for DC/DC switching regulator applications, supporting step-up, step-down, and step-up/step-down configurations. This device operates over a wide voltage range of 7V to 35V and can achieve oscillator frequencies up to 600kHz.

 

Key features include dual 200mA source/sink outputs, programmable soft-start, under-voltage lockout, and thermal shutdown protection. The UC3526ADW is suitable for various topologies such as Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull.

 

Packaged in an 18-SOIC (0.295", 7.50mm Width) surface-mount package, it operates within a temperature range of 0°C to 70°C. The part is noted as 'NOT RECOMMENDED FOR NEW DESIGNS'.
