UC3526ADWTR Description

Short technical summary and product information.

The UC3526ADWTR from Texas Instruments is a pulse-width modulator (PWM) controller IC. It is designed for power management applications, supporting functions such as Step-Up, Step-Down, and Step-Up/Step-Down configurations. The device operates with an input voltage range of 7V to 35V and can achieve frequencies up to 600kHz.

 

Key features include dual 200mA source/sink outputs, synchronous rectification capability, and control features like Enable, Frequency Control, Reset, and Soft Start. The UC3526ADWTR is housed in an 18-SOIC package and is designed for surface mount applications. It operates within a temperature range of 0°C to 70°C.

 

This PWM controller is suitable for various topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations. It also includes features like under-voltage lockout and thermal shutdown for protection. Note that this part is not recommended for new designs.
