I bought, TPS63020 Automatic Step Up Down Buck Boost Power Board Module Low Ripple 2.5V 3.3V 4.2V 5V Lithium Battery, a breakout board for the TPS63020.
It says online
"PS: Point-saving mode (1 is disabled, 0 is enabled, and the module is disabled by default). If you want to use this function, you need to disconnect SB1, and then input the level"
"EN: Enable input (1 is enabled, 0 is disabled, and the module is enabled by default). To use this function, disconnect SB2, and then input the level"
To me this meant I could use the board with no further connections. There is a curse in the TI documentation, EN and PS "must not be left open".
In use, there appeared to be no output voltage. Looking at the board closely, as supplied SB1 and SB2 are open links.
To be clear, for this item to work, EN and PS levels must be set up externally (or, I have not tried it, via making the links).
There are some more links to the right, these apparently select the output voltage 2.5, 3.3, 4.2 and 5.0V (3.3V shown selected).
