UC2525ADWTR Description

Short technical summary and product information.

The Texas Instruments UC2525ADWTR is a versatile PWM controller designed for various switching power supply topologies including Boost, Flyback, Forward, Full-Bridge, Half-Bridge, and Push-Pull. It operates over a wide voltage range of 8V to 35V and features an adjustable switching frequency from 100Hz to 400kHz, with a maximum duty cycle of 49%.

 

Key features include an internal 5.1V reference trimmed to 1%, adjustable dead-time control, internal soft start, and pulse-by-pulse shutdown. The device also includes undervoltage lockout with hysteresis and latching PWM to prevent multiple pulses. It is equipped with dual source and sink output drivers.

 

This controller is available in a 16-SOIC package and is designed for surface mount applications. The operating temperature range is -25°C to 85°C.

 

It is suitable for designing efficient and reliable switching power supplies, offering improved performance and reduced external component count.
