Enable-Control Inputs (EN1, EN2)
The MAX17113 EV kit features jumpers JU3 and JU4 to
control the two switching regulators and the two charge-
pump regulators’ enable inputs. Jumper JU3 controls the
step-down and negative charge-pump regulator enable
input (EN1). Jumper JU4 controls the step-up and posi-
tive charge-pump regulator enable input (EN2). EN2 is
inactive when EN1 is low. See Table 4 for jumper JU3
and JU4 functions.
High-Voltage Switch-Control Input (CTL)
Jumper JU5 configures the setting to control the high-
voltage switch-control pin (CTL) of the MAX17113 IC.
The switch between the SRC and GON pins and the
switch between the GON and DRN pins can also be con-
trolled by an external logic controller connected to the
CTL pad. See Table 5 for switch states and refer to the
High-Voltage Switch Control section in the MAX17113 IC
data sheet for further information about the high-voltage
switches connected to the GON pin.
VGON Discharge Path
The MAX17113 EV kit features a method to configure the
VGON discharge path using resistor R15 and jumper
JU6. When CTL is low, GON is connected to DRN, allow-
ing VGON to discharge through resistor R15. JU6 selects
the discharge path by connecting R15 to AVDD (through
diode D6) or to PGND. Table 6 lists the selectable JU6
jumper options.
Positive Charge-Pump Stage Selection
Jumper JU7 is provided to select between a positive
dual-stage charge pump and a positive single-stage
charge pump. Table 7 lists the selectable JU7 jumper
options.
High-Voltage Switch-Control Block
Output (GON)
Jumper JU8 is provided to connect or disconnect a
bypass capacitor to the high-voltage switch-control
block output GON terminal. Table 8 lists the selectable
JU8 jumper options.
