TPS26630-33EVM: Evaluation Module for TPS2663x
3 General Configurations
3.1 Physical Access
Table 3 lists the TPS26630-33EVM input and output connector functionality, Table 4 describes the test
point availability and Table 5 describes the jumper functionality.
Table 3. Input and Output Connector Functionality
Connector Label Description
T1 CH1 VIN1(+), GND(–) CH1 input power supply to the EVM
T2 VOUT1(+), GND(–) CH1 output from the EVM
T3 CH2 VIN2(+), GND(–) CH2 input power supply to the EVM
T4 VOUT2(+), GND(–) CH2 output from the EVM
NOTE: For testing with continuous input voltage greater than 33 V, remove TVS diode D2 (for CH1)
and D7 (for CH2) and install diodes of appropriate voltage rating.
For testing with continuous input voltage greater than 50 V, diodes D2 and D7 and
capacitors C3 and C7 have to be replaced with diodes and capacitors of appropriate voltage
rating.
