I am also interested to know if the LM3405 features open circuit protection. I am using the LM3405 to drive multiple sets of LEDs at different times. I select what LED to drive by opening/closing some FETs acting as switches. There will be small periods…

Hi,
Attached is the schematic and BOM of a 11.#v, 850mA LED driver using LM3405A.
The input voltage is 16.5V at 1 Amp.
Can somebody let me know if the design is ok, and if i can proceed…
Part Number: TPS92613-Q1 Other Parts Discussed in Thread: LM3405 , TPS92200 , LM3405A Hi,
I am planning to use TPS92613-Q1 to drive a resistive load which takes 0.55A@5V.
My input voltage is from 5V adapter.
The main reason for slecting the driver…
Part Number: LM5108 Other Parts Discussed in Thread: LM3404 , LM3405A , TPS28225 , LMR16010 , LMR51625 Is it possible to use the LM5108 for an asynchronous buck regulator? To use the high-side MOSFET but a freewheeling diode instead of the low-side MOSFET…
Part Number: TPS54200 Other Parts Discussed in Thread: LM3405A Hi TI,
I'm trying to design a driver for a laser diode and in the chart below you see some test results with TPS54200 and LM3405A. I need to keep the current below 600mA.
Unfortunately…
Other Parts Discussed in Thread: LMR62014 , LM3405A Using your LMR62014, we designed a circuit that boosts to 5V -> 12V.
It is designed in the same way as the connection plot on the two pages of the datasheet. (10uF added to input)
However, when the…
Part Number: LM3401 Other Parts Discussed in Thread: LM3405 , LM3405A , LM3404 , LM3414 I am helping a customer to find a driver suitable for multiple LEDs in series. Usually 5 LEDs. The voltage of each LED is 2.5V-2.8V. Could you please help recommend…
Part Number: TPS92200 Other Parts Discussed in Thread: TPS54200 , LM3405A , LM3405 , TIDA-01415 , LM3409 Hi, I am working on a laser diode driver for 3 red and 3 infra-red, total of almost 5w.
This is applied in a medical device used for photo therapy…
Part Number: LM3410 Other Parts Discussed in Thread: LM3405A , LM3405
Is it possible to create analog dimming with LM3410, by adding an analog offset to the feedback?
(see attached sketch)
The step-down LM3405A can be handled this way, but there…
Hi Na,
I could not find problem on your customer's schematic.
Did they try powering the LED with our EVM (by changing the inductance and resistance to suit their need)?
I suspect there might be layout issue or component codings' different from…
