20-48-Vdc input isolated flyback reference design with a 48-V: 1.25-A output
Description
This reference design uses the LM3481 to provide an isolated 48-V output from a DC input ranging from 20 to 48-V. Its low profile design makes it suitable for applications where a small solution size is critical. The design achieves over 91% efficiency at a nominal 0.8-A load: and can provide a pulse up to 1.25-A.
Features
- Over 91% efficient when delivering a 48-V: 0.8-A load with 20-V and 48-V input voltage casesLess than 1% ripple on output at full loadWide input range1500-Vrms isolationLow profile design with 18-mm maximum height
