Table 1-2. Test Points (continued)
Test Point Description
UDIM2 (TP14)
UDIM2 test point allows for the direct connection of the UDIM2 pin of the TPS92520-Q1. UDIM2 test point allows for
external PWM dimming signals to control channel 2 assuming J8 is unloaded. This test point can also be used to
monitor the PWM signal generated from the LEDMCUEVM-132 for channel 2 assuming J8 is loaded.
