SC471: Synchronous Buck Controller With Multi-Level VOUT Transition Support | Semtech

The SC471 A is a versatile, constant on-time synchronous buck, pseudo-, xed-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, programmable over-current protection, soft shutdown, Automatic power save and non-overlapping Gate drive. The SC471 A provides an enable input and a power good output which is automatically blanked during output voltage transitions. By Semtech Corporation
