UC1527B Overview
The UC1525B/1527B series of pulse width modulator integrated circuits are designed to offer improved performance and lowered external parts count when used in designing all types of switching power supplies. The on-chip +5.1V buried zener reference is trimmed to ±0.75% and the input mon-mode range of the error amplifier includes the reference voltage, eliminating external resistors.
