Introduction

The NBM2317 bus converter evaluation board described in this document is designed to be used with
the NBM2317S60D1580T0R, SM-ChiP non-isolated, fixed-ratio, bidirectional DC-DC bus converters.
Note: Refer to UG:701 for NBM2317S60E1560T0R evaluation board user guide.
The focus of this document is to assist the user in evaluating of the NBM2317 SM-ChiP™ family.
The NBM™ evaluation board can be configured for various enabling and fault monitoring schemes, as
well as to exercise various loading conditions depending on the application requirements. The evaluation
board can be used to evaluate NBMs in stand-alone configuration.
It is important to remember that the fast response of NBMs can readily show the limitations of the
source, load and associated wiring connected to the evaluation board. Care should be taken to minimize
the source impedance as well as high- and low-voltage side interconnect impedances in order to fully
realize the NBM performance.
The NBM non-isolated topology allows start up in step-down and step-up directions and provides
bidirectional protections. However, if the powertrain is disabled by any fault protection and low
side voltage V is present, a voltage V
