Key Document


The LM5015 Non-Isolated DC-DC Regulator evaluation board provides a low cost and fully functional DC-DC regulator without employing any discrete power MOSFET. The evaluation board can be configured as either a Non-Isolated Two-Switch Forward DC-DC Regulator, or a Two-Switch Flyback DC-DC Regulator. The factory default configuration of the evaluation board is Forward topology. The former configuration will produce about 2% higher efficiency and lower output ripple voltage than the flyback. Whereas, the Flyback configuration costs slightly less. Suggestion to reconfigure the evaluation board as an Non-Isolated Two-Switch Flyback DC-DC Regulator is provided at the end of this article.

  • Input voltage: 36V to 72V
  • Isolated output voltage: 5V
  • Output current: 0A minimum, 2.5A nominal, and 3A maximum
  • Input UVLO threshold: 34V nominal
  • Measured efficiency: 86% (VIN = 48V, IOUT = 2.5A)
  • Switching frequency: 300 kHz
  • Ability to synchronize to external clock
  • Ability to be remote controlled (enable/disable)
  • Two layer PC board and top side component placement configurable as either a forward (factory default) or a flyback regulator
  • Board size (WxLxH): 2.5 in. x 3.5 in. x 0.63 in
