24VDC Input (Dual Automotive Batteries) Automotive Multi-Phase Synchronous Buck Reference Design

PMP10260

Overview

This efficient, high-power reference design uses the LM5119 dual-phase synchronous buck controller to regulate 14.4V at 60A. This design can be used to feed a single vehicle battery source from a dual-battery system commonly found in trucks. Features include input EMI filtering, output hot-swap protection, input/output current monitoring, and temperature monitoring.

characteristic

● The efficiency is 96% when the input voltage is 24V and 60A output
● Extremely low output ripple voltage (20mVpp)
● Internal 5V bias supply provides up to 0.5A current
● Input and output current monitoring
●Output overcurrent protection
