6) Connect dummy load between the VOUT and GND

pads located on the EV kit. Adjust the load to 250mA.

7) Verify that a shunt is installed on pins 2-3 of jumper

JU1 to enable the MAX5092B.

8) Verify that a shunt is installed pins 2-3 of jumper

JU2 to disable the

HOLD function of the

MAX5092B.

9) Turn on PS1 and sweep the input voltage from 4V to

7V to 3.5V as indicated on the input DVM. Verify

that the BSOUT DVM indicates approximately 7V

over the input-voltage range. Verify that the VOUT

DVM indicates approximately 5V over the input-volt-

age range. Note that the MAX5092 still properly

regulates the outputs with VIN as low as 3.5V after

the IC is started.

10) Reduce the dummy load to 10mA.

11) Increase PS1 to 7V.

12) Warning: Dangerous voltages are present on the

EV kit during this step. Sweep the PS1 voltage

from 7V to 72V. Verify that the BSOUT DVM voltage

follows the input DVM voltage, minus a diode drop,

over the input-voltage range. Verify that the VOUT

DVM indicates approximately 5V over the input-volt-

age range.

13) Optional procedure to observe the MAX5092 low-

a) Set the PS1 voltage to 14V. The boost converter

is not switching.

b) Turn off PS1. Caution: Do not turn on the power

supply until all connections are complete.

c) Remove the load from VOUT.

d) Remove all the DVMs to eliminate the DVM con-

e) Remove the wire between PS1 and the VIN pad

on the EV kit.

f ) Connect the positive terminal of PS1 to the posi-

tive terminal of the ammeter. Connect the nega-

tive terminal of this ammeter to the VIN pad

g) Turn on PS1. Observe that the ammeter indicates
