SG3525N - Pulse Width Modulator Control Circuit

Download the SG3525N datasheet PDF. This datasheet also covers the SG3525 variant, as both devices belong to the same pulse width modulator control circuit family and are provided as variant models within a single manufacturer datasheet.

Key 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 ca.

SG3525 Pulse Width Modulator Control Circuit The SG3525 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.
