SG3525A Overview
Pulse Width Modulator Control Circuit SG3525A The SG3525A pulse width modulator control circuit offers improved performance and lower external parts count when implemented for controlling all types of switching power supplies. The on−chip +5.1 V reference is trimmed to "1% and the error amplifier has an input mon−mode voltage range that includes the reference voltage, thus eliminating the need for external divider...
