Description
The SC412A 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 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, programmable over-current protection, soft shutdown, automatic power save and non-overlapping gate drive. The SC412A also provides an enable input and a power good output. Features
VBAT Range 3V to 25V So.
