4000Vac Isolated Fly-Buck Power Converter for Medical Applications Reference Design

Overview

TopologyFlyBuck (Double Buck)
Input voltage6-14 V
Output 15.6 V / 0.12 A
IC revisionA

Description

The PMP10563 reference design is a single output isolated Fly-Buck power supply for Medical applications. It takes 12V nominal input and provides 5.6V 0.12A output. The minimum input voltage can go down to 6V. The design features the LM5160 synchronous buck converter configured as a Fly-Buck regulator. With the benefit of primary side regulation, the power supply can sustain 4000Vac isolation voltage between primary and secondary. At the same time, it can control secondary voltage changes of ±5%.

Features

  • Single 5.6V 0.12A output
  • 4000Vac isolation voltage between primary and secondary
  • Wide input voltage range of 6V to 14V
  • 83% peak efficiency at 0.67W output power
  • Good load regulation without op-to coupler
