SG3525 Pulse Width Modulated Control

SG3525 is a pulse width modulated control circuit that is used to control switching power supplies and particularly helps in providing lower external parts count and improved performance.

It is voltage control PWM controller in which feedback voltage is compared with reference value which then controls the duty cycle of PWM.
Mainly used in inverter applications and utilizes two main PWM outputs that are inversion of each other.
