Description

The ST1S10PUR is a high-efficiency step-down PWM current-mode Switching Regulator capable of providing up to 3A of output current. The device operates with an input supply range from 2.5 to 18V. It operates either at a 900kHz fixed frequency or can be synchronized to an external clock (from 400kHz to 1.2MHz). 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.
