SC191
SC191 is Low Supply Ripple Synchronous Buck Conversion Regulator manufactured by SEMTECH.
Low Supply Ripple Synchronous .. Buck Conversion Regulator
POWER MANAGEMENT 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 the SC191 ideal for single-cell Li-ion battery applications as well as fixed 3.3V and 5V fixed input applications. The output is a fixed 1.2V
- ideal for low-voltage...
