SC475A - Synchronous Buck Controller

General Description

The SC475A is a versatile, constant on-time synchronous buck, pseudo-fixed-frequency, PWM controller intended for notebook computers and other battery operated portable devices.

Key Features

  • needed to provide cost-effective control of system elements needing voltage slewing. An integrated switch provides two resistorprogrammable DC output voltages controlled by the G0 input. www. DataSheet4U. com SC475A Features VOUT Programmable 0.75V to 5.25V with Integrated Transition Support VBAT Range 3V to 25V Soft Shutoff at Output Current Sense Using Low-side RDS(ON) or Resistor Sensing Adjustable Cycle-by-Cycle Valley Current Limit 325kHz Fixed-Frequency Constant On-Time for Fast Dynamic Re.
