Description

The PMP10822 reference design utilizes two QR flyback, and four buck converters. The efficiency for the 12V and 24V flyback approaches 87%, while the 16V buck converter has efficiency greater than 89%.

Features
  • The 12V and 24V flyback converter's efficiency approaches 87% at full load, with an input of 120VAC
  • The 16V buck converter's efficiency is greater than 89% at full load, with a 24V input
  • Board length is approximately 3.45" x 4.95"
  • Test report is available
