LM5171-Q1 EVM User Guide
The LM5171EVM-BIDIR Evaluation Module (EVM) is designed to showcase the LM5171-Q1 high performance
dual-channel bidirectional controller suitable for, but not limited to, the automotive 48-V to 12-V dual battery
system applications.
The EVM can be configured as a bidirectional power converter in the form of either a current source or voltage
source. The direction of power flow can be controlled either by an external command signal or by the on-board
jumper. Through the onboard interface headers, the EVM can be operated by a DSP, an FPGA, an MCU, or
other digital controllers. Two EVMs can be paralleled to make a 3 or 4 phases interleaved converter for higher
power. More EVMs can be paralleled for greater number of phases. Many convenient jumper headers are also
included for versatile configurations of the EVM.
Refer to the
LM5171-Q1 Multiphase Bidirectional Current Controller Data Sheet
