PMP10260 Reference Design

Texas Instruments

24Vdc Input (Double Car Battery) Automotive Multiphase Sync-Buck Reference Design


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.

  • Efficiency of 96% at Vin = 24V and 60A outputVery low output ripple voltage (20mVpp)Internal 5V bias supply provides up to 0.5AInput and output current monitoringOutput over-current protection
  • Automotive external amplifier
  • Voltage conditioning module
  • Aftermarket audio amplifier
