The ST1S30 is a 3A, 1.5MHz PWM step-down switching regulator with synchronous rectification function launched by ST
The ST1S30 is a step-down DC-DC converter optimized for low output voltage applications, supplying a current in excess of 3 A over an input voltage range from 2.7 V to 6 V. It features a high 1.5 MHz PWM switching frequency to allow the use of tiny surface-mount components and includes an integrated synchronous rectifier to minimize external component count.
