Coin Battery Boost


CT21100 is high efficiency DCDC boost converter delivering 2.7V at 10mA from an input as low as 0.9V. Designed to work with a single alkaline/NiMh coin cell. To improve efficiency with light load conditions, an asynchronous topology with Pulse Frequency Modulation (PFM) technique is implemented.

  • Input Voltage Range: 0.9V to 1.8V
  • (single alkaline or Ni-MH battery)
  • 10 mA maximum output
  • 18 uA quiescent current with no load.
  • Fixed 2.7V output voltage.
  • Modulation (PFM) technique.
