ST1S10PHR Product Details
ST1S10PHR Description

The ST1S10PHR is a high efficiency step-down PWM current mode switching regulator capable of providing up to 3 A of output current. The ST1S10PHR device 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 ST1S10 provides excellent transient response, and is fully protected against thermal overheating, switching overcurrent and output short-circuit. The ST1S10PHR is the ideal choice for point of load regulators or LDO pre-regulation.
