The ST1S10PHR is a high efficiency step-down PWM current mode Switching Regulator with inhibit function. The device operates with an input supply range from 2.5 to 18V and provides an adjustable output voltage from 0.8V. It operates either at a 900kHz fixed frequency or can be synchronized to an external clock. 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 regulator IC provides excellent transient response and is fully protected against thermal overheating, switching over-current and output short-circuit.
● 2% DC output voltage tolerance
● Synchronous rectification
● Internal soft start
● Dynamic short-circuit protection
● 90% Typical efficiency
●ESD sensitive device, take proper precaution while handling the device.
