SC191, Low Supply Ripple Synchronous Buck Conversion Regulator
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 provid
SC191 Features
* include internal soft-start to limit inrush current, over-current protection, over-temperature protection, and over-voltage protection. The 1MHz switching frequency allows the use of small surface mount capacitors and inductors, and no other external compensation components are needed. The device is
