LM5170-Q1 EVM User Guide

The LM5170EVM-BIDIR Evaluation Module (EVM) is designed to showcase the LM5170-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 to achieve a bidirectional power converter in the form of either the 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 LM5170-Q1 Multiphase Bidirectional Current Controller Datasheet (SNVSAQ6) for detailed technical information of the LM5170-Q1 device.
