Jumper Selection
Several jumper settings in the following tables illustrate
features of the MAX17115 EV kit.
Enable Control Input (EN)
Connect EN to AGND to disable the step-up switching
regulator operation. Connect EN to VIN to enable the
boost operation. See Table 1 for jumper JU1 functions.
Frequency Select Input (FREQ)
Connect FREQ to AGND to select the step-up regula-
tor’s 640kHz operating frequency. Connect FREQ to
VIN to select the step-up regulator’s 1.2MHz operating
frequency. See Table 2 for jumper JU2 functions.
High-Voltage Stress Control Input (HVS_EN)
Connect HVS_EN to VIN to turn on the internal switch
between RHVS and AGND. Connect HVS_EN to AGND
to make the RHVS pin high-impedance. See Table 3 for
jumper JU3 functions.
High-Voltage Switch Control Input (VFLK)
When VFLK is connected to VIN, the high-voltage switch
between VGH and VGHM is on and the high-voltage
switch between VGHM and DRN is off. When VFLK
is connected to AGND, the switch between VGH and
VGHM is off and the switch between VGHM and DRN is
on. See Table 4 for jumper JU4 functions.
