Description

The PMP10861 uses active clamp forward converter for an isolated 24V to 12V/3.4A conversion. Reverse input connection, output over-current protection, output over-voltage protection, input inrush current limiting circuit are integrated in this board. With wide 9-36V input voltage range, over 89.5% peak efficiency is achieved with 24V input voltage. All the components temperature rise are less than 30oC at full load condition.

Features
  • 24V to 12V/3.4A active clamp forward converter
  • 9V to 36V input voltage range
  • Integrated protections: reverse input connection, output over-current protection, output over-voltage protection
  • Peak 89.5% efficiency with 24V iinput
  • Test report available
