7 Test Points and Sense Locations
7.1 VIN/VOUT test points
Input voltage should be measured at test points TP7/TP29/K15 (position 7c)
which are connected directly to the VIN/GND pins of MAIN module (PHASE 1) at
the Test board. Alternative test points are TP25/TP26, connected to VIN/GND
pins of PHASE 2 at the Test board.
Output voltage can be measured at test points TP27/TP28/K16 (position 7a)
which are directly connected to VOUT/GND pins of MAIN module (PHASE 1) at
the Test board. Alternative test points are:
- TP15/TP16/K14 (position 7b), connected to VOUT/GND pins of center
positioned electronic load (position 10).
- TP24/TP23/K18, connected to VOUT/GND pins of PHASE 2 at the Test
board.
7.2 Sense location jumpers
Sense location jumpers in J13/J14 (position 16) must be correctly placed
according to VOUT test points used:
- Use positions “MAIN” when measuring VOUT at TP27/TP28/K16.
- Use positions “LOAD” when measuring VOUT at TP15/TP16/K14.
If no jumpers are populated, internal sense resistors in MAIN module will be used.
7.3 PWM test points
PWM test points in position 18 can be used to probe a PWM signal to each MAIN
or SATELLITE module, to see if it is currently switching or not.
