Part Number: TPS92690 Other Parts Discussed in Thread: TPS92692-Q1 Hello,
This is very early on in debugging with a customer so I am trying to get a lot more information. What I have heard is that some issues are being seen with driving resistive loads…
Part Number: TPS92690 Hello,
I am looking to drive a Bridgelux (BXRC-50C4001-B-74-SE) COB but have been having issues with the calculations for the inductor etc., mostly because the equations are based off of the "resistance" of an individual LED…
Part Number: TPS92690 Other Parts Discussed in Thread: LM3404 , , TPS92691 , TPS92692 Hi David,
Based on your reply for LM3404, I can use TPS92690 to drive 7pcs OSRAM SFH4726 LEDs(Vf=2.75V, If=1A max) when my input voltage is 12V, right? Is this the lowest…
Part Number: TPS92690 On the datasheet, it looks like equation 18 and equation 20 on pages 15 and 16 on the datasheet are incorrect. Can you verify that it's supposed to be Vturn-off = 1.24*(R_ov1+Rov2)/Rov1 for equation 18 and Vturn-on=1.24*(Ruv1+Ruv2…
