SC191: Low Supply Ripple Synchronous Buck Conversion Regulator | Semtech

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 ef, ciency. 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 , xed 3.3V and 5V , xed input applications. The output is a , xed 1.2V - ideal for low-voltage Microprocessors Other voltage options are available (consult the factory for details). By Semtech Corporation
