SC191 Description
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 maximize efficiency. The internal MOSFET switches provide peak current greater than 550mA to achieve a DC output of at least 330mA over the rated input voltage range, making...
