Hi, Nathan
Thank you for your quick reply.
Yes, there is no problem even if it is not connected to the LED driver. Currently, LED drivers consume more current than I thought.
When the LED bar is connected and measured in my application, 760mA is measured…
Hi Hailiang,
My mistake...it's LM3405A, but he maximum input voltage is 24V.
If this device still can not meet your requirements, please consider LM3404 or LM3414.

Part Number: TPS92511 Other Parts Discussed in Thread: LM3405A , TPS92513 Hi
We have following design requirement.
VIN:12V
VLED: 2.2V
RFS:3.3K
RIADJ : 4.3K (0.35A as led current)
L : 200uH
These specification will offer Iripple = 0.029App that would…
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 are issues…
You would need a buck driver for 12V input and 1 LED output. The smallest I am aware of would be the LM3405 or LM3405A. They are in a SOT package and switch at 1.6MHz so the externals can be small. The only difference between the two really is the maximum…
Other Parts Discussed in Thread: LM3406HV , LM3406 , TPS92513 , LM3405A , LM3424 , TPS92691 Hello,
Is it possible for me to use the LM3406HV with a solenoid as the load instead of an LED?
The solenoid characteristics are below:
Inductance: 22mH
Resistance:…

Hi,
Earlier in first prototype we had LM3404 LED drivers for driving RGBW LED's. As per design the RON pin was contiously kept high whereas the DIM pin was controlled…
I don't know how you can do it with MP2370 but I can tell you that:
- our LM3405A ( http://www.ti.com/lit/ds/symlink/lm3405a.pdf ) is the Texas Instrument equivalent part of MP2370
- you can use an oring connection with a proper input cap; the LED driver…
