ST1S06 - Synchronous rectification

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.

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.
