Overview

Our integrated circuits and reference designs help you design highly reliable, cost-effective merchant telecom rectifiers with ultra-high energy efficiency, high power density and redundancy.

Design requirements

Innovative merchant telecom rectifiers often require:

  • High efficiency with soft-switching techniques, bridgeless PFC topologies or GaN devices.
  • Small size and high-power density.
  • High system reliability with less thermal stress.
  • Digital solution with CAN, RS-485 or Bluetooth®/NB IoT for scalability and connectivity.
