The MAX1543 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
DC power supply between +2.6V and +5.5V that can
provide at least 2A. The switching frequency is jumper

selectable between 600kHz and 1.2MHz. The EV kit
also evaluates the MAX1542 after replacing IC U1.
As configured, the step-up switching regulator (VMAIN)
generates a +8V output and can provide at least
250mA from a +2.6V input. It also provides at least
300mA from a +3.0V input and 500mA from a +5V
input. The step-up switching-regulator output voltage
can be adjusted up to +13V with other feedback resis-
tors (see the Output-Voltage Selection section).
The GON supply consists of two positive charge-pump
stages to generate approximately +22V and can pro-
vide greater than 20mA. The GOFF supply consists of a
single negative charge-pump stage to generate
approximately -7V and can provide greater than 20mA.
The operational amplifier outputs, VOUT1 and VOUT2,
are set to +4V and can source or sink approximately
150mA. These two outputs can be reconfigured to
other voltages by changing the voltage-divider resistors
(see the Output-Voltage Selection section).
The high-voltage switch between the SRC and COM pins
can be used to delay the GON output startup. The GON
voltage is connected to the source of the switch (SRC),
