The SG3525AP is a pulse width modulator (PWM) controller made by STMicroelectronics with an output driver that can provide up to 100mA at 5V. It is a small outline 16-pin package with an operating supply voltage of 8–35V. Features include two independent channels, an onboard frequency-compensation circuit, phase-locked loop circuitry, and protective circuitry. It can be used in a wide range of power-supply designs, such as switch-mode power supplies, motor-control circuits, and inverter applications.
