SC471A - Synchronous Buck Controller

Download the SC471A datasheet PDF. This datasheet also covers the SC471 variant, as both devices belong to the same synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

Description

The SC471/A is a versatile, constant on-time synchronous buck, pseudo-fixed-frequency, PWM controller intended for notebook computers and other battery operated portable devices.

Features

  • needed to provide cost-effective control of system elements needing voltage slewing. Two integrated switches provide four resistor-programmable DC output voltages, controlled by the G0 and G1 inputs. The output voltage is adjustable from 0.75V to 5V. Additional features for each output include cycle-by-cycle current limit, voltage soft-start, under-voltage protection, programmable over-current protection, soft shutdown, automatic power save and non-overlapping gate drive. The SC471/A provides an.
