The TPS922051/0 evaluation module (EVM) is a two-layer PCB assembly with multiple variants to help the user evaluate the main features and performance of the TPS922051/0 device family. The TPS922051/0 is a 2A / 1A non-synchronous Buck 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 TPS922051/0 EVMs, including TPS922051D1DSGREVM, TPS922051D2DSGREVM, TPS922050D1DSGREVM, TPS922050D2DSGREVM, TPS922051D1DGNREVM, TPS922051D2DGNREVM, TPS922050D1DGNREVM, TPS922050D2DGNREVM, TPS922050D1DRLREVM and TPS922050D2DRLREVM.
