UC1525B-SP Overview
Description
The UC1525B pulse width modulator integrated circuit is designed to offer improved performance and lowered external parts count when used in designing all types of switching power supplies. The on-chip 5.1-V buried zener reference is trimmed to ±0.75%, and the input common-mode range of the error amplifier includes the reference voltage, eliminating external resistors.
