The SG3525A Pulse Width Modulator Control circuits, It is a pulse width modulation controller IC which has 16 pins. It provides two pulse width modulator signal which is a complement of each other. It is used to generate a PWM signal for power electronics projects and also for switch-mode power supplies. It offers feedback circuitry to control the output voltage by comparing the feedback signal with a reference voltage. It has a protection circuitry that shutdown the PWM signal based on the feedback current limit.

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. This device also features built−in soft−start circuitry, requiring only an external timing capacitor. A shutdown pin controls both the soft−start circuitry and the output stages, providing instantaneous turn off through the PWM latch with pulsed shutdown, as well as soft−start recycle with longer shutdown commands. The under voltage lockout inhibits the outputs and the changing of the soft−start capacitor when VCC is below nominal. The output stages are totem−pole design capable of sinking and sourcing in excess of 200 mA. The output stage of the SG3525A features NOR logic resulting in a low output for an off−state.
