SC471 Product details

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.
