Description

The LM27403 EVM is a 300-kHz, high efficiency, synchronous buck converter with voltage-mode control and inductor DCR current sensing for overcurrent protection. An inexpensive 2N3904 BJT is used to sense temperature at the inductor. This enables correction for the inductor DCR’s variation over temperature as well as provide a thermal shutdown function based on a desired temperature setpoint.

Features
  • 25A output current
  • 3V to 20V input voltage range
  • Switching frequency 250kHz
  • High efficiency, 91%, 1.2V 25A
  • DCR current sensing with temperature compensation
