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.
