Product Summary

The ST1S10BPHR is a monolithic synchronous step-down regulator. The ST1S10BPHR operates with an input supply range from 2.5 V to 18 V and provides an adjustable output voltage from 0.8 V (VFB) to 0.85VIN_SW [VOUT = VFB(1+R1/R2)]. It operates either at a 900 kHz fixed frequency or can be synchronized to an external clock (from 400 kHz to 1.2 MHz). The high switching frequency allows the use of tiny SMD external components, while the integrated synchronous rectifier eliminates the need for a Schottky diode. The ST1S10BPHR provides excellent transient response, and is fully protected against thermal overheating, switching over-current and output short circuit. The ST1S10BPHR is the ideal choice for point-of-load regulators or LDO pre-regulation.
