ST1S30 Datasheet PDF (PWM step-down switching regulator)

ST1S30 - PWM step-down switching regulator

Description

The ST1S30 is a step-down DC-DC converter optimized for powering low output voltage applications.

It supplies a current in excess of 3 A over an input voltage range from 2.7 V to 6 V.

A high PWM switching frequency (1.5 MHz) allows the use of tiny surface-mount components.

Features

1.5 MHz fixed frequency PWM with current control mode.
3 A output current capability.
Typical efficiency: > 90%.
2 % DC output voltage tolerance.
Two versions available: power good or inhibit.
Integrated output over-voltage protection.
Non switching quiescent current: (typ. ) 1.5 mA over temperature range.
RDSon (typ. ) 100 mΩ.
Utilizes tiny capacitors and inductors.
Operating junction temp. -25 °C to 125 °C.
