Install between pins 1 and 2 to short out D1 (for normal operation). Remove when testing the
J1
OVP feature using S1.
Select the desired EN and FLT pullup resistor supply source using a shunt on J2 per the
schematic diagram. When the shunt is in the IN position, then the pullup source is connected
J2 to the IN pin. When the shunt is in the IO position, then an external IO source should be
connected between TP11 and J7 (or another GND test point). For extended high voltage
pulse testing, use the IO position with a supply voltage below 7 V.
Select the desired current limit using a shunt on J3 per the schematic diagram. When the
ILIM
shunt is removed, the current limit is approximately 850 mA.
COUT Select the desired output capacitance using a shunt on J4 per the schematic diagram.
EN Remove the shunt to enable the TPS25200 and install the shunt to disable.
