4000Vac Isolated Fly-Buck power converter for medical applications reference design

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 opto coupler

Parts Include:
LM5160   Wide Input 65V, 1.5A Synchronous Step-Down DC-DC Conv
