SG3525 Circuits SG3525 Projects SG3525 pulse width modulator PWM control integrated, can be used for the control of all kinds of switched power supply. High performance. A synchronization input to the oscillator allows multiple units to be supplied or a single unit to be synchronized to an external system clock. A wide range of dead time control can be performed with a single resistor connected between the Frequency and Discharge pins, plus a built-in soft start circuit set by an external timing capacitor.
