SC196 - 1.5A Synchronous Buck Converter

Description

The SC196 is a synchronous step-down converter with integrated power devices designed for use in applications using a single-cell Li-ion battery.

Its wide input voltage range also makes it suitable for use in systems with fixed 3.3V or 5V supply rails available.

1.5A Synchronous Buck Converter with Integrated www.DataSheet4U.com Power Devices POWER MANAGEMENT Description The SC196 is a synchronous step-down converter with integrated power devices designed for use in applications using a single-cell Li-ion battery. Its wide input voltage range also makes it suitable for use in systems with fixed 3.3V or 5V supply rails available. The switching frequency is nominally set to 1MHz, allowing the use of small inductors and capacitors. The current rating of the internal MOSFET switches allows a DC output current of 1.5A. The output voltage is set by connecting a resistor divider from the filter inductor to the feedback pin. See the SC196A for pin-programmable output voltages.
