Description

This high-efficiency, high-power reference design uses the LM5119 two-phase synchronous-buck controller to regulate 14.4V at 60A. This design can be used to supply single car battery power from a double battery system, often found in trucks. Features include input EMI filtering, output hot swap protection, input/output current monitoring and temperature monitoring.

Features
  • Efficiency of 96% at Vin = 24V and 60A output
  • Very low output ripple voltage (20mVpp)
  • Internal 5V bias supply provides up to 0.5A
  • Input and output current monitoring
  • Output over-current protection
