Key Document


This boost converter implements a voltage tripler which allows a high input-to-output boost ratio. This design is low cost and requires an area of less than 25mm x 25mm.

  • Excellent efficiency (>82% with 10mA load at 12Vin)
  • Implements 100V components with low stress
  • Low output ripple voltage (<0.4%)
  • Small 25mm x 25mm area
