![ONSEMI SG3525A Pulse Width Modulator Control IC (SMD Package)](http://www.electronifyindia.com/cdn/shop/files/MDI01AA.webp?v=1710143453&width=1445)
Description
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 common−mode voltage range that includes the reference voltage, thus eliminating the need for external divider resistors. A sync input to the oscillator enables multiple units to be slaved or a single unit to be synchronized to an external system clock. A wide range of deadtime can be programmed by a single resistor connected between the CT and Discharge pins.
