STMicroelectronics ST1PS01FJR, 1-Channel Buck, Sync Buck Converter, 400 mA, 1.05V 2 MHz, Flip-Chip 8-Pin

Buck Step Down Converter

The STMicroelectronics ST1PS01 is a nano-quiescent miniaturized synchronous step-down converter, which is able to provide up to 400 mA output current with an input voltage ranging from 1.8 V to 5.5 V. This converter is specifically designed for applications where high efficiency, PCB size and thickness are the key factors. The output voltage can be set using two digital control inputs, a VOUT from 0.625 V to 3.3 V can be dynamically selected.

• Low power control operation for the best efficiency
• Embedded soft-start circuit
• Tiny external components L=2.2 μH typ.
• Selectable output voltages 0.625 V to 3.3 V
