SC196A 1.5A Synchronous Buck Converter

The SC196A is a synchronous step-down converter with integrated power devices. The SC196A is designed for single-cell Li-Ion battery applications but can also be used in ﬁxed 3.3V or 5V applications. The switching frequency is nominally set to 1MHz, allowing the use of small inductors and capacitors.
