Input is the protected power input terminal for the converter with a voltage range from 4V-40V. The
terminal block provides a power (Vbat) and ground (GND) connection to allow the user to attach the EVM
to a cable harness. The power path provides a series Schottky diode for reverse battery protection.

VOUTA is the output terminal for the TPS4335x buck controller A. The terminal block provides a
power (VOUTA) and ground (GND) connection.
J3
–
VOUTB is the output terminal for the TPS4335x buck controller B. The terminal block provides a
power (VOUTB) and ground (GND) connection.
JP5
–
ENA is the jumper used to enable buck controller A. The controller will be enabled when the ENA is
high and disabled when low.
