AN2620
Application note
3 A high-frequency synchronous 900 kHz
step-down converter based on the ST1S10

Introduction
The ST1S10 is a step-down DC-DC converter with an optimized inhibit function for powering
high-voltage LCD applications and low-voltage digital core HDD applications. Generally, it
replaces the high current linear solution when high power dissipation is a problem. It
provides up to 3 A over an input voltage range of 2.5 V to 18 V and synchronous rectification
saves the external Schottky diode.
