SC191 regulator equivalent, low supply ripple synchronous buck conversion regulator.
include internal soft-start to limit inrush current, over-current protection, over-temperature protection, and over-voltage protection. The 1MHz switching frequency allow.
as well as fixed 3.3V and 5V fixed input applications. The output is a fixed 1.2V - ideal for low-voltage microprocessors. .
The SC191 is a synchronous step-down converter with integrated power devices and an integrated front-end LDO regulator to minimize input supply ripple. If supply ripple is not a concern, the front-end LDO regulator can be bypassed externally to maxim.
