Setup Instructions for the ISL6271A Evaluation Kit

Initial Set-Up

Position the ISL6271A eval board so that the Intersil logo is in the upper right corner, relative to testers perspective.

All switch positions on S1 should be to the ‘left’ to Enable the device for static VID input.

Place shunts as follows, (see Figure 1):

H1 to ‘enable’

H2 no shunt (if external LVCC being supplied, left two pins should never be shorted)

H3 no shunt

H4 no shunt

FIGURE 1. SHUNT PLACEMENT ON H1 TO ENABLE, AND NO SHUNT ON H2, H3 AND H4

Adjust the External Power Supplies to 3.7V and 2.5V respectively, and turn off.

NOTE: (Under NO circumstances should the voltage on either supply be allowed to exceed 6.0V)

Adjust the external electronic load for a constant current of 200mA (Do not interconnect).

Connect J1 on the eval board to the dual power supply, with the (LVCC+) pin to 2.5V (supply to the 2 LDO’s), the (+)

pin to 3.7V (supply to the swiching regulator), and the (-) pin to the supply common (gnd), Figure 2.
