REF_5BR4780BZ_15W1

概要

15W non-isolated flyback auxiliary power supply for residential outdoor aircon

The REF_5BR4780BZ_15W1 is an auxiliary power supply reference design configured in a flyback topology and is based on the ICE5BR4780BZ, a product of Infineon’s 5th generation fixed frequency CoolSETTM family.

The power supply supports an input range up to 264 VAC with 15 V / 150 mA, 12 V / 800 mA and 5 V / 300 mA non-isolated output. Thanks to the integrated 800 V MOSFET, such a design enables the deployment to unstable grid environments and increases system robustness.

特長

  • Universal input 85~264 VAC
  • Output #1: 15 V / 150 mA
  • Output #2: 12 V / 800 mA
  • Output #3: 5 / 300 mA
  • > 75% full-load efficiency @ 230 VAC

利点

  • Multi-output support for IPM gate driver, relay, MCU and miscellaneous biasing needs
  • Ease of design and BOM reduction thanks to an integrated error amplifier
  • Robust operation with an integrated 800 V MOSFET
