1.5A Synchronous Buck Converter with Integrated www.DataSheet4U.com Power Devices POWER MANAGEMENT Description 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. The maximum current rating of the internal MOSFET switches allows a DC output current of 1.5A. Four programable output voltages 1.00V/1.05V/1.20V/ 1.80V are available. See SC196 with external feedback for other output voltage settings. The SC196A has a flexible clocking methodology that allows it to be synchronized to an external oscillator or controlled by the internal oscillator.
