製品概要

概要

The ST1PS03 is a nano-quiescent miniaturized synchronous step-down converter, which is able to provide up to 400 mA output current with an input voltage ranging from 1.8 V to 5.5 V. This converter is specifically designed for applications where high efficiency, PCB size and thickness are the key factors.

The output voltage can be set using three digital control inputs, a VOUT from 1.6 V to 3.3 V can be dynamically selected. Thanks to the enhanced PCC (peak current control) the ST1PS03 reaches very high efficiency conversion using just a 2.2 µH inductor and two small capacitors. An advanced design circuitry is developed to minimize the quiescent current. The device embeds a controlled switch accessible from VIN_AUX, to supply a subsystem. Finally, it is available in thin plastic package.

  • 特徴

    • 500 nA input quiescent current at VIN = 3.6 V (not switching)
    • 92% typical efficiency at 10 mA load (VIN = 3.6 V, VOUT = 2.5 V)
    • 100% duty cycle
    • 1.8 V to 5.5 V input operating range
    • Undervoltage lockout: 1.57 V (VIN falling, typ.)
    • Up to 400 mA output current capability
    • Low power control operation for the best efficiency
    • Embedded soft-start circuit
    • Tiny external components: L = 2.2 µH typ.
    • Selectable output voltages: 1.6 V to 3.3 V
    • Output voltage Power Good
    • ±1.5% output voltage accuracy (VOUT, TA = 25 °C)
    • Dynamic output voltage selection (D0, D1 and D2)
    • Load switch controlled by AUX input
    • Available in TQFN12 package
