ST1S06A - Synchronous rectification

Download the ST1S06A datasheet PDF. This datasheet also covers the ST1S06 variant, as both devices belong to the same synchronous rectification family and are provided as variant models within a single manufacturer datasheet.

General Description

The ST1S06xx is a step down DC-DC converter optimized for powering low-voltage digital core in HDD applications and, generally, to replace the high current linear solution when the power dissipation may cause an high heating of the application environment.

Key Features

  • Step-down current mode PWM (1.5 MHz) DCDC converter.
  • 2% DC output voltage tolerance.
  • Synchronous rectification.
  • Inhibit function.
  • Internal soft start.
  • Typical efficiency: > 90 %.
  • 1.5 A output current capability.
  • Not switching quiescent current: max 1.5 mA over temperature range.
  • RDS(ON) typ.150 mΩ.
  • Uses tiny capacitors and inductors.
  • Operative junction temp. - 30 °C to 125 °C.
  • Available in DFN6D (3x3 mm) exposed pad.
