Si9177 - Vishay Power ICs

Si9177 - Vishay Power ICs SI9177 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-H 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 to turn on at 100% duty cycle, overriding the FB signal. The voltage differential between input and output is the resistive voltage drop on the internal 150-m PMOS and the inductor. The SI9177 delivers 800-mA load in bypass mode. The SI9177 is available in the space saving MLP33-10 and MSOP-10 packages. In order to satisfy the stringent ambient temperature requirements, the SI9177 is rated to handle the industrial temperature range of -25C to 85C. By Vishay Intertechnology
