Part Number: LM2665 Tool/software: What is the polarity of the SD shutdown signal? The documentation says that when the SD signal is grounded the converter is on. This makes sense. However, section 6.5 in the March 2016 datasheet says the part is in shutdown…
Part Number: LM2665 Hello TI Team,
We trying to simulate LM2665 IC based voltage doubler circuit on WEBENCH but it is not supported. See below screen shot of issue.
We simulate below circuit using this LM2665 IC.
Please support this issue…
Part Number: LM2665 Hi,
I am considering LM2665M6/NOPB since LM2665M6 has NRND status. Could you tell me the difference between these two products?
Thanks,
Conor
Part Number: LM2665 Dear Team： My customer want to used LM2665 turn 3.3V to 8V, and the design as below, is this circuit correct?
What does D1 do?
Thanks!
Regards!

Hello Brigitte,
I added the 4.7 kohm resistor at the output of the LM2665 (in series), after the output cap, to greatly add to the global output impedance. As there is (not shown) a MOSFET between the 10V rail and GND, the resistor allows me to crash…
Part Number: LM2665 I have a 5V rail and want to charge a 2.7V supercapacitor. It looks reasonable to use the LM2665 to generate 2.5V (Vin/2) and use that to charge the capacitor. My question is whether I can rely on the 40mA max current of the LM2665…
Part Number: LM2665 Hi Team,
What's the maximum output voltage when using cascading structure?
Customer spec:
VIN = 5V
Vout = 15V @ 30mA
What's the alternative solution? What's the suggestion for cap C1/C2/C3 and Cout? Please provide capacitor…
Part Number: LM2665 Other Parts Discussed in Thread: LM2765 , LM2681 Team,
My customer is looking to add a 2nd source alternative to LM2665M6X/NOPB on the current design. We would be second sourcing ourselves in this case. So, question is - do we have…
Part Number: LM2665 Hello Team,
One of my customer was using TC1240AECHTR which does not require external diode for start up. We suggested LM2665 as an alternate which has same pin out. however, as per LM2665 datasheet, it requires a general purpose…
Part Number: LM2665 Hi,
Can I check for some supporting measurement data on:
(1) Power efficiency at 1.4V, 2~4mA condition. According to datasheet, it should be 90% min, with typical 94%.
(2) Shutdown current
Typ 1uA, what is the maximum…
