POWER MANAGEMENT Description
The SC194B is a synchronous step-down converter with integrated power devices.
Four selectable output
voltages suitable for portable device interface, memory function blocks, and 5V to 3.
3V
voltage conversion are available.
Automatic selection of Power Save Mode (PSAVE) is supported which enhances efficiency.
A 100% duty cycle mode allows operation for input
voltages close to the required output
voltage.
The need for external components is minimized by providing internal feedback compensation, and allowing selection of the required output
voltage by hard wiring VID code inputs.
