2.4.1 J13 EN

EN is a 3-pin header used to enable or disable the TPS7B84-Q1, which in turn supplies ADJ for the TPS7B4261-Q1.

The center pin of the 3-pin header is tied to the TPS7B84-Q1 EN input. When the 2-pin shunt is placed across the right two pins of the header, VIN is shorted to EN and the TPS7B84-Q1 is enabled. When the 2-pin shunt is placed across the left two pins of the header, GND is shorted to EN and the TPS7B84-Q1 is disabled.

If the TPS7B84-Q1 is not to be used to supply the ADJ signal for the populated tracker, remove jumper J12 and use TP3 to drive ADJ directly, or a combination of J6, R2, R4, C10 to configure ADJ to be a function of the input voltage.
