UC1526AJ Description

Short technical summary and product information.

The UC1526AJ from Unitrode is an improved-performance pulse-width modulator circuit. It is designed for direct replacement of equivalent non-"A" versions in various applications. This device supports multiple topologies including Boost, Flyback, Forward, Full bridge, Half bridge, and Push pull.

 

Key electrical features include a precision band-gap reference, dual 200mA source/sink outputs, and operation from 7 to 35V. It offers programmable soft-start, under-voltage lockout, and thermal shutdown protection. The oscillator frequency can operate up to 600kHz, with a maximum duty cycle of 50%.

 

The UC1526AJ is available in LCCC (FK) and CDIP (J) packages, suitable for surface mount applications. It is noted as not recommended for new designs, with the TL494 listed as a similar alternative.

 

This component is suitable for AC/DC switching regulators and DC/DC power modules. Its features make it adaptable to a range of power management applications requiring precise pulse width modulation control.
