调整脉冲宽度调制器 Regulating Pulse Width Modulator

DESCRIPON

The UC1526A Series are improved-performance pulse-width modulator circuits intended for direct replacement of equivalent non- “A” versions in all applications. Higher frequency operation has been enhanced by several significant improvements including: a more accurate oscillator with less minimum dead time, reduced circuit delays particularly in current limiting, and an improved output stage with negligible cross-conduction current. Additional improvements include the incorporation of a precision, band-gap reference gener ator, reduced overall supply current, and the addition of thermal shutdown protection.
