hello,i have one question about the BUCK BOOST circuit of the tps92692
i would like to know What role does the PNP transistor in the picture play?why add this PNP transistor?
thank you
best regards
Hello,
The PNP is to take the differential voltage of LED+ and LED-. This is the LED load voltage and that's what you are sensing for over-voltage.
Thanks Tuan
