UC2525ADW Description

Short technical summary and product information.

The Texas Instruments UC2525ADW is a pulse width modulator (PWM) integrated circuit designed for various switching power supply applications. It offers improved performance and a reduced external parts count.

 

Key electrical specifications include an operating voltage range of 8V to 35V and a frequency range from 100Hz to 400kHz. The device features a 5.1V reference trimmed to 1% and supports multiple topologies such as Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull. Control features include Enable, Frequency Control, and Soft Start.

 

This controller is housed in a 16-SOIC package and is designed for surface mount applications. The operating temperature range is -25°C to 85°C. The UC2525ADW is marked as obsolete and not recommended for new designs.

 

It is suitable for applications requiring efficient power conversion and regulation in a compact form factor.
