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 computers 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 protection,...
