3.6 Connectors and Terminal Blocks Description
Table 4 presents pin connection for each header present on the KITVR500EVM.
Table 3. Jumper Description
Jumper Default Description
J6 Closed
Shorts PVIN and SWVIN. Allows supply isolation to provide more accurate efficiency readings on the switching
supplies
J7 Closed Shorts PVIN to VIN. Allows one to isolate or connect the 34VR500 logic input supply to PVIN net. (debugging option)
J8 Closed Short EN to the MCU
J9 Open Short to pull STBY to PVIN voltage supply
J10 Open Short to hold EN pin low
J11 Open
Shorts SWVIN to VIN. Allows one to isolate or connect the 34VR500 logic input supply to SWVIN net. (debugging
option)
J12, J13, J14 Closed Short to connect VLDOIN to VIN
J15 Closed Short to connect SCL and SDA to the MCU
J16 Closed Short to connect EN to PVIN
J17 1 - 2
VCCI2C Supply selector
• 1-2: Connect VCCI2C to 3V3 LDO
• 3-4: Connect VCCI2C to SW2 output
J19, J23, J24
Closed
Buck regulators input power path isolation
Short these jumpers to allow PVINx to be powered from the SWVIN supply
J22
1 - 2
3 - 4
Buck regulators input power path isolation
J25 2 - 3
Control Interface input supply selector
• 1-2: Enables PVIN node as the input supply source for the control interface
• 2-3: Enables USB power as the input supply source for the control interface
