It has a pulse to pulse shutdown capability.
Sg3525 is used in Dc to DC converter part to control the output voltage and for switching of MOSFETS connected to push-pull converter chopper. I have used a voltage mode PWM controller in pure sine wave inverter. While the current control method uses Output current from output inductor to compare it with the reference value and to set the duty cycle of PWM. In return to control the output voltage of SMPS. The voltage control method used a feedback voltage by comparing it with a reference value to set a duty cycle of PWM. There are two types of PWM controller integrated circuits: I will discuss these things in detail later in this article. These PWM controllers ICs you can use very easily in your SMPS projects by connecting some external circuitry with them according to the selection of frequency. There are many PWM ( Pulse width modulation ) controller integrated circuits available in the market just like SG3525.
