Procedure
2) Verify that there is a shunt installed across jumper
3) Verify that there are shunts installed across JU4 and
4) Connect the positive terminal of the power supply to
5) Turn on the power supply and verify that the step-
6) Verify that the gate-on supply (VP) is approxi-
7) Verify that the gate-off supply (VN) is approxi-
8) Verify that the operational-amplifier output (VCOM)
9) Verify that the high-voltage switch common (GON)
For instructions on selecting the step-up switching regu-
lator feedback and op-amp divider resistors for other out-
put voltages, see the Output-Voltage Selection section.
The MAX8758 EV kit contains a step-up switching regu-
lator, a positive two-stage charge pump, a negative sin-
gle-stage charge pump, two operational amplifiers, and
a high-voltage switch matrix. The EV kit operates from a
+2.2V to +5.5V DC power supply that can provide at
least 2A. The switching frequency is jumper selectable
