SC412A - Synchronous Buck Controller

SC412A Description

SC412A Synchronous Buck Controller POWER MANAGEMENT .
The SC412A is a versatile, constant on-time synchronous buck, pseudo fixed-frequency, PWM controller intended for notebook computers and other battery.

SC412A Features

* needed to provide cost-effective control of switch-mode power outputs. The output voltage is programmable from 0.75 to 5.25 external resistors. Switching frequency is internally preset to 325kHz. Additional features cycleby-cycle current limit, voltage soft-start, under-voltage protection, programma
