4.9

J3 – VLDO1/GND

This header is the output of LDO1. This output voltage is internally fixed for the TPS650001/3/6 (see

Table 1

). VLDO2 is capable of sourcing up to 300-mA. A load can be connected between J3 pins 1 and 2

(positive connection) and J3 pins 3 and 4 (GND).

4.10 J4 – VLDO2/GND

This header is the output of LDO2. This output voltage is internally fixes for the TPS650001/3/6 (see

Table 1

). The default setting on the EVM is 2.8-V. VLDO2 is capable of sourcing up to 300-mA. A load

can be connected between J4 pins 1 & 2 (positive connection) and J4 pins 3 & 4 (GND).

4.11 J5 – PG

JP5 is pulled to GND if the output voltages of the DCDC converter and both LDOs are > 90% of their set
point and all enable pins are pulled high.

JP5 pulled up to the selected pull-up voltage level if any of the output voltages VODCDC, VLDO1 or
VLDO2 is <90% of its set point or all enable pins are pulled low

present typical performance curves for the TPS650001/3/6. Since actual

performance data can be affected by measurement techniques and environmental variables, these curves
are presented for reference and may differ from actual field measurements.
