3 A, 900 KHz, Monolithic Synchronous Step-down Regulator

The ST1S10 is a high efficiency Step-down PWM current mode Switching Regulator capable of providing up to 3 A of output current. The device operates with an input supply range from 2.5 V to 18 V and provides an adjustable output voltage from 0.8 V (V ) to 0.85*V [V = FB IN_SW OUT V *(1+R1/R2)]. It operates either at a 900 kHz FB 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 over-current and output short circuit. The ST1S10 is the ideal choice for point-of-load Regulators or LDO pre-regulation. By STMicroelectronics
