Compact low-loss isolated four-output flybuck reference design

Description

This four output flybuck reference design the LM25017 synchronous buck converter to provide four 3.3 V: 82.5 mW outputs. Each output has 1.25 kV isolation and is regulated to 1% accuracy. A low profile transformer and low BOM count create a compact solution size.

Features
  • Four 1.25 kV isolation: which mitigates noise between outputs1% accuracy on each 3.3 V output: to meet high precision specificationsCompact design with low profile transformer: which allows for easy integration into end systemLess than 750 mW losses with all outputs at full load: which provides efficent power conversion
