製品概要

概要

The ST1S32 is an internally compensated 1.5 MHz fixed-frequency PWM synchronous step-down regulator. The ST1S32 operates from 2.8 V to 5.5 V input, while it regulates an output voltage as low as 0.8 V and up to VIN.

The ST1S32 integrates a 60 mΩ high-side switch and a 45 mΩ synchronous rectifier, allowing very high efficiency with very low output voltages.

The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.

The ST1S32 is available in 4 mm x 4 mm, 8-lead VFDFPN package.
