5.6 Output Connections

1. Connect the load to J1, J5, and J6, and set the load to constant resistance mode to sink 0 Adc before

5Vin and 12VBAT are applied. This is for CPU operation.

2. Connect a voltmeter V3 at J14 to measure CPU Vcore sense voltage.

6 Configuration

All jumper selections must be made prior to applying power to the EVM. The user can configure this EVM

per the following configurations.

6.1 CPU and GPU Configuration

6.1.1 CPU/GPU Current Limit Trip Selection (J17 for CPU and J20 for GPU)

The current limit trip can be set by J17 (COCP) and J20 (GOCP).

Default setting: Level 5 for both CPU and GPU.

Table 2. Current Limit Trip Selection

Left (1-2 pin shorted) 150k Max

Second (3-4 pin shorted) 100k Level 7

Third (5-6 pin shorted) 75k Level 6

Fourth (7-8 pin shorted) 56.2k Level 5

Fifth (9-10 pin shorted) 39.2k Level 4

Sixth (11-12 pin shorted) 30.1k Level 3

Seventh (13-14 pin shorted) 24.3k Level 2

Right (15-16 pin shorted) 20.0k Min
