Sales Briefcase
  • The STEVAL-1PS01AJR evaluation board features the ST1PS01 miniaturized, nano-quiescent, synchronous step-down converter designed for applications where high efficiency, PCB size and thickness are the key factors. The converter can provide up to 400 mA output current with a 1.8 V to 5.5 V input voltage range. The output voltage can be dynamically adjusted from 1.9 V to 2.8 V using two digital control inputs.

    Thanks to the enhanced peak current control (PCC), the ST1PS01 can achieve very high efficiency conversion using only a 2.2 µH inductor and two small capacitors. Furthermore, the converter's advanced design circuitry reduces quiescent current to a minimum.

    Key Features

    • 1.8 V to 5.5 V input operating range
    • Up to 400 mA output current capability
    • Tiny external components: L=2.2 µH typ.
    • Selectable output voltages: 1.9 V to 2.8 V
    • Output voltage Power Good
    • Dynamic output voltage selection (D0, D1)
    • Suitable for the following applications:
      • Wearable applications
      • Personal tracking monitors
      • Smart watches, sport bands
      • Energy harvesting, wireless sensors
      • Wearable and fitness accessories
      • Industrial sensors, portable low power devices
      • Single cell Li-Ion battery applications
      • Bluetooth® low energy
      • Zigbee
    • WEEE and RoHS compliant (hardware only)
