Key Features

  • Ultra-Low Quiescent Current: Typical 360nA quiescent current, making it suitable for low-power applications.
  • DCS-Control™ Topology: Combines the advantages of hysteretic and voltage mode control for excellent AC load regulation and transient response.
  • High Efficiency: Up to 90% efficiency at 10µA output current, extending high efficiency operation to very low load currents.
  • Selectable Output Voltage: Output voltage is selectable in 100mV steps from 1.8V to 3.3V using four VSEL pins.
  • Low Output Ripple Voltage: Low noise operation with a small output capacitor.
  • Automatic Transition to No Ripple 100% Mode: The device enters no ripple 100% mode operation when the battery voltage approaches the output voltage.
  • Slew Rate Controlled Load Switch: Integrated load switch with a typical on-resistance of 0.6Ω.
  • Power Good Output: Indicates when the output voltage is within the specified range.
  • Small Solution Size: Total solution size less than 31mm² with a tiny 2.2µH inductor and 10µF output capacitor.

Applications

  • Bluetooth® Low Energy, RF4CE, Zigbee: Suitable for wireless communication devices requiring low power consumption.
  • Industrial Metering: Used in industrial metering applications where power efficiency is crucial.
  • Energy Harvesting: Ideal for energy harvesting systems due to its high efficiency at low load currents.
  • Low Power MCU and RF Subsystem (Sensors): Supports low power microcontrollers and RF subsystems in sensor applications.
