2.1.7 TP4 – PG_FB

Feedback pin test-point connection.

Note:

As implemented in Section 5, with R3 and R7 set to 10 kΩ, and with the programmable current limit set to 100% of ILIMIT, the PG pin goes up when the output voltage reaches 50% of the targeted value.

For a complete implementation of both the PG pin and the current limit, see the TPS7A94 data sheet.
