MxC110

The MxC110 is a two-chip production solution using Helix’s patented MuxCapacitor technology targeted for use in 65W AC-DC power supply products supporting USB-C PD3.0 applications. The chipset is designed for use with Flyback, Forward and other transformer-based power supply architectures.  For highest efficiency Secondary Converter solutions, Helix offers a third chip, a Synchronous Rectifier Controller.

The MxC110 supports traditional opto-isolator feedback using a Proportional-Integral-Derivative (PID) loop controller with the added capability of dynamic feedback control to maximize the power efficiency.

The chipset enables the management of no-load conditions to meet or exceed a Zero Power requirement of < 5mW. Proprietary Helix technology is used to effectively manage the no-load power dissipation while still maintaining the output voltage at the specified value.

In short, the MxC110 enables 65W transformer-based AC-DC power supply solutions for multiple end applications with end-to-end average efficiency greater than 95%.

Typical applications include:

  • USB-C Compatible Output Voltages
  • Smart Outlets
  • IoT and IIoT Gateways
  • Remote Sensors
  • Smoke and CO Detectors
