EVM User's Guide

TPS923651/0 65V 2A/1A Boost/Buck-Boost LED Driver Evaluation Module with PWM/Analog Dimming

Description

The TPS923651/0 evaluation module (EVM) is a two-layer PCB assembly with multiple variants to help the user evaluate the main features and performance of the TPS923651/0 device family. The TPS923651/0 is a 2A / 1A non-synchronous Boost / Buck-Boost LED driver with 4.5V to 65V wide input range with PWM / analog dimming function. By integrating the low-side NMOS, the device is capable of driving LEDs with high power density and high efficiency. This document includes setup guidance, schematics, printed-circuit board (PCB) layouts, and bill of materials (BOM) for the whole family of TPS923651/0 EVMs, including TPS923651D1DSGREVM, TPS923651D2DSGREVM, TPS923650D1DSGREVM, TPS923650D2DSGREVM, TPS923651D1DGNREVM, TPS923651D2DGNREVM, TPS923650D1DGNREVM, TPS923650D2DGNREVM, TPS923650D1DRLREVM and TPS923650D2DRLREVM.
