UCC25702PW Description

Short technical summary and product information.

The UCC25702PW from Texas Instruments is a voltage mode PWM controller intended for isolated switching power supplies. It is suitable for both off-line applications and DC/DC converter designs. This controller operates at a 700kHz switching frequency and offers a maximum duty cycle of 99%.

 

Key features include adjustable switching frequency, current limiting, multi-topology support, programmable maximum duty cycle, soft start, and a synchronization pin. It provides a 1A peak gate drive output and has low start-up and operating currents. The device also incorporates voltage feed-forward compensation for fast response to input voltage changes and an accurate volt-second clamp.

 

The UCC25702PW is available in SOIC, TSSOP, and PDIP packages. It operates within a temperature range of -40°C to 85°C. This controller is designed for efficient off-line starting and has sufficient output drive for switching power MOSFETs at high frequencies.
