    ICsense has successfully carried out various DC-DC developments in different technologies for a range of applications:

    • Inductive and capacitive
    • Buck, boost, buck/boost and flyback (with external transformer)
    • Current mode - voltage mode
    • Continuous - discontinuous conduction mode (CCM - DCM)
    • Synchronous - asynchronous
    • Controllers (with an external power device) and converters (fully integrated)
    • Low-voltage designs and high-voltage designs (> 70V)
    • Currents ranging from 100µA to 1-2A.

    All these developments involved custom designs. Example target applications are Power-over-Ethernet, power management for cell phones, solar charging of cell phones, power management for medical implants, power management for audio applications and wireless applications.
