CT21104 is high efficiency DCDC boost converter designed work with Li-Ion batteries. The boost converter is optimized for current load  up to 20mA and 3.3V to 15V selectable output voltage (2V of step).

Regulation is performed fixed frequency voltage mode PWM technique. The CT21104 is designed to work with best efficiency in Discontinuous Conduction Mode (DCM).


  • Input Voltage Range: 1.62V to 5.5V
  • 20mA of Load Current
  • 3V to 15V Selectable Output (2V of Step)
  • Voltage regulation performed according fixed 600KHz frequency voltage mode PWM technique
  • 6mV ripple output voltage with 10uF x5R output capacitor
  • 75% of efficiency at 20mA of load with 1.8V input and 15V output
