The MAX15005A EV kit features an OVP circuit that pre-
vents operation above the programmed V_ANODE out-
put supply voltage (136V default). Jumper JU3 config-
ures the circuit for output OVP protection when the
shunt is placed across pins 2-3. Resistors R11 and R12
set the OVI threshold of the OVP circuit for the
MAX15005A IC. To evaluate other OVP voltages,
replace resistor R11 with another surface-mount resis-
tor (0603 size). Using the desired OVP voltage, resistor
R11 is then found by the following equation:
where OVP is the desired voltage that the circuit shut-
down is at and resistor R12 is typically in the 10kW
range (12.1kΩ default). See Table 3 for configuring
jumper JU3 for output OVP protection.
The MAX15005A EV kit OVP circuit can be reconfigured
to provide load dump protection for VIN when it rises
above the programmed VIN supply voltage (24.7V
default). Jumper JU3 configures the circuit for input
OVP protection when the shunt is placed across pins 1-
2. Resistors R12 and R20 set the OVI threshold of the
Input OVP Shutdown (Load Dump Protection)

MAX15005A Evaluation Kit
OVP circuit for the MAX15005A IC. To evaluate other
OVP voltages, replace resistor R20 with another sur-
face-mount resistor (0603 size). Using the desired OVP
voltage, resistor R20 is then found by the following
equation:
where OVP is the desired voltage that the circuit shut-
down is at and resistor R12 is typically in the 10kΩ
range (12.1kΩ default). See Table 3 for configuring
jumper JU3 for input OVP protection.
