Datasheet Summary
Synchronous Buck Controller with Multi-Level VOUT Transition Support
POWER POWERMANAGEMENT MANAGEMENT Description
The SC471/A is a versatile, constant on-time synchronous buck, pseudo-fixed-frequency, PWM controller intended for notebook puters and other battery operated portable devices. The SC471/A contains all the 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...
