Other Parts Discussed in Thread: LM3424, INA149
Dear team,
I have some problem on TPS92692:
1, In data sheet, inductor, output capacitor and input capacitor selection are calculated based on output power, which are unlike others such as lm3424, and I can not understand the equation given in data sheet. (P27-P28 in datasheet)
2, In the over voltage protection circuit in buck-boost topology use a PNP, why?(P26 in datasheet)
3, What is the meaning of rD, "LED string dynamic resistance", how to calculate or acquire it?
thank you!
