BOOST consists of a step-up boost regulator with the following features.

  • Low voltage startup, even from a battery with high internal resistance
  • Flexible and power efficient operating modes
    • High Power (HP)
    • Low Power (LP)
    • Ultra-Low Power (ULP)
    • Pass-through (PT)
  • Pin selectable initial output voltage 1.8 V and 3.0 V
  • Configurable output voltage in 50 mV steps from 1.8 V to 3.3 V
  • Overcurrent protection (OCP) for pass-through operation
