ST1S03 Overview
Description
The ST1S03 is a step-down DC-DC converter optimized for powering a low voltage digital core in HDD applications and, generally, to replace the high current linear solution when the power dissipation may cause a high heating of the application environment. It provides up to 1.5 A over an input voltage range of 3 V to 16 V.
Key Features
- Step-down current mode PWM (1.5 MHz) DC-DC converter
- 2% DC output voltage tolerance

- Typical efficiency: > 70% over all operating conditions
- 1.5 A output current capability
- Not switching quiescent current: max 2.5 mA over temperature range
- Switch VDS: max. 350 mV at ISW = 750 mA
- Uses tiny capacitors and inductors
- Available in DFN6D 3 x 3 mm package with exposed pad Datasheet
- production data
