  • The ST1S06 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. It provides up to 1.5 A over an input voltage range of 2.7 V to 6 V. An high switching frequency (1.5 MHz) allows the use of tiny surface-mount components: as well as the resistor divider to set the output voltage value, only an inductor and two capacitors are required. Besides, a low output ripple is guaranteed by the current mode PWM topology and by the use of low ESR SMD ceramic capacitors. The device is thermal protected and current limited to prevent damages due to accidental short circuit. The ST1S06 is available in DFN6D 3x3 package.

    Key Features

    • Uses tiny capacitors and inductors
    • RDS(ON) typ150mΩ

    • 1.5A Output current capability
    • Typical efficiency:> 90%
    • Step-down current mode PWM (1.5MHz) DC-DC converter
    • Synchronous rectification
    • 2% DC output voltage tolerance
    • Internal soft start
    • Not switching quiescent current: max 1.5mA over temperature range
    • Inhibit function
