Supply
The input voltage range for the converter is VBATP = VBAT_SAFING = 5.8 volts to 36 volts. It should be
supplied to CON1, pin 1 (VBAT_SAFING) and 3 (VBATP) with respect to pin 2 and 4 (GND).

Jumper Setting
For proper operation of the TPS65381-Q1 device, the jumper should be properly configured. The
recommended setting is shown in the table below.
J NO.
J1
Connect VBAF_SAFING to VBATP.
J2
Use VSOUT1 as follower or with gain.
J3
Select the tracking input.
J4
Select the VDDIO voltage.
J5
Select output voltage VDD3/5.
J6
IGN supported by TIGER board and SPI
connector CON3.
CON2, pin 4
Connector 2 (pin 4) is the IGN pin; must be Remove the jumper to use the EVM together with
connected to CON2, pin 4 to turn the DUT
on.
(1)
For start-up without using the TIGER board or external IGN signal, IGN (pin 4 of CON2) can be connected to VBATP (pin 6 of
CON2) by setting a jumper to start up the device.
