SG3525A Pulse Width Modulator Control IC (SMD Package) PRICE IN PAKISTAN

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 onˆ‚¬„¢chip +5.1 V reference is trimmed to ±1% and the error amplifier has an input commonˆ‚¬„¢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.
