SLVUBX9 October 2020 TPS2640
The TPS2640EVM enables full evaluation of the TPS2640 devices. The EVM supports HTSOP and QFN versions of the devices on two channels (CH1 and CH2, respectively). Input power is applied at T1 (CH1) and T3 (CH2) while T2 (CH1) and T4 (CH2) provide an output connection to the load. See the schematic in Figure 3-1 and the test setup in Figure 4-1.
S1 and S2 allow U1 and U2 to RESET. A fault
(FLTb) indicator is provided by D1 and D7 for CH1 and CH2, respectively. Scaled
current for each channel can be monitored at TP5 and TP14 with a scaling factor
of
1.5 V / A.
