UC1525AJ Description

Short technical summary and product information.

The UC1525AJ from Texas Instruments is a regulating pulse width modulator integrated circuit designed for switching power supplies. It offers a wide operating voltage range of 8V to 35V and includes an on-chip 5.1V reference voltage trimmed to 1% accuracy.

 

Key features include an oscillator range from 100Hz to 500kHz, adjustable dead-time control, internal soft start, and pulse-by-pulse shutdown input. The device also incorporates undervoltage lockout with hysteresis and latching PWM to prevent multiple pulses. It provides dual source and sink output drivers.

 

This IC is available in CDIP (J) and LCCC (FK) packages. Note that the UC1525A is not recommended for new designs, though it remains available for existing customers. Consider alternate products for new projects.
