This header is the output of the step-down converter. This output voltage is externally adjustable for the
TPS65001. The default setting on the EVM is 1.2V. VODC is capable of sourcing up to 600-mA. A load
can be connected between J2 pins 1 and 2 (positive connection) and J2 pins 3 and 4 (GND).

can be connected between J2 pins 1 and 2 (positive connection) and J2 pins 3 and 4 (GND).
The input power supply has to be connected to this header. The power supply must be connected
between J3 pins 1 and 2 (positive connection) and J3 pins 3 and 4 (GND). The leads to the input supply
should be twisted and kept as short as possible. The input voltage has to be between 3.3-V and 6-V.

J4 pin 1 is connected to the open drain output RST of the Supply Voltage Supervisor.
RST is pulled low if either manual reset input MR is low or the voltage on RSTSNS is below the threshold.
If manual reset MR is released or the voltage on RSTSNS rises above the threshold voltage RST goes
high again after the reset recovery time t

This header is the input supply for LDO2. Placing a shorting bar between VINLDO2 and VINDC/VODC
supplies LDO2 from VIN with R12. It can be also supplied from the output of the converter VODC with
R13 (not assembled). An external power supply can be connected between J5 pin2 (VINLDO2) and pin3
(GND). Note that the resistors R12 and R13 should be removed when supplying the LDO from an external
power supply.
