2 Description

The TPS1653EVM enables full evaluation of the TPS16530 device. This EVM has two independent channels (CH1 and CH2) where two devices can be evaluated together. CH1 accommodates the TPS16530PWPR device while CH2 accommodates the TPS16530RGER device. Input power is applied at T1 (CH1) and T3 (CH2) while T2 (CH1) and T4 (CH2) provide the output connections to the load respectively. Refer to the schematic in Figure 5-1 and EVM test setup in Figure 3-1. S1 and S2 allow U1 and U2 to be reset or disabled and Jumper J4 and J11 allow the current limit setting to be changed.

A fault (FLTb) indicator is provided by D3 and D7 for CH1 and CH2, respectively. Scaled current for each channel can be monitored at TP7 and TP16 with a scaling factor of 0.83 V / A.
