UC1524AJ Description

Short technical summary and product information.

The UC1524AJ from Unitrode is an advanced, double-ended, voltage mode PWM controller. It is designed to offer improvements over the industry-standard UC1524, while remaining pin-compatible for easy integration into existing designs. This controller supports multiple topologies including Boost, Flyback, Forward, Full bridge, Half bridge, and Push pull configurations.

 

Key electrical specifications include a maximum duty cycle of 50%, an output current capability of up to 200mA, and a wide output voltage capability of 60V. It features an internal reference trimmed to ±1% accuracy, a high-performance current limit function, and under-voltage lockout with hysteretic turn-on. The start-up supply current is less than 4mA, and it offers a guaranteed frequency accuracy and thermal shutdown protection.

 

Available in CDIP (J) and LCCC (FK) packages, the UC1524AJ is suitable for through-hole mounting. Its operating temperature range is from -55°C to 125°C, making it robust for demanding environments. The controller includes features like an error amplifier, soft start, and synchronization pin, providing designers with enhanced control and flexibility.
