The Si9177 is a dual-mode power adjustable output converter. When it is set to PSM mode, the Si9177 operates as a pulse-skipping-modulation controlled step-down (buck) converter with an output voltage range of 1.2 V to 5 V. It has an integrated MOSFET, capable of supplying 200-mA load current with a 1.5-mH inductor. The output voltage is adjusted by a resistive divider on the FB pin. The typical conversion efficiency is above 90%. A logic HIGH at the BP/PSM pin puts Si9177 in bypass mode. The main PMOS buck switch is forced |
