SG3525 Overview
SG3525 Pulse Width Modulator Control Circuit The SG3525 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...
