Other Parts Discussed in Thread: LM3406HV My purpose is to drive three different string of RGB LEDs with the same chip, in order to select different colors, which can vary in time. Since the LEDs are very sensitive to thermal stress and in order not to…
Other Parts Discussed in Thread: LM3406 Hi,
I would like to confirm the operation of start-up for LM3406.
"Start Up using OFF Terminal" waveform is mentioned in the "LM3406 EVM Use's Guide".
The IF is constant after start-up.

Other Parts Discussed in Thread: LM3406 I've been trying to get some troubleshooting through my local reps and they finally directed me here. Essentially I'm using a LM3406 to buck a 14.8V battery down to power some monster LED array at 9.6V/1A. I can…
Other Parts Discussed in Thread: LM3406 On my project I'm using CREE 162 RGB led's connected Green and Blue 6 in series each, total 26 strings of 6 on each Green, same on Blue. My voltage is 24VDC each Green/ blue led current is 20ma and 3.2v on…
Other Parts Discussed in Thread: LM3406LM3406 datasheet page 4: Electrical characteristics > Internal regulator > Vcc-lim. The parameter is Vcc current limit; the test conditions are Vin=24V, Vcc=0V. Min is 4mA, typ is 20mA. The test conditions…
Other Parts Discussed in Thread: LM3405 , LM3406 Hi, I'm trying to power an LCD backlight LED with a current source and control it with PWM. I was considering the LM3405 but now I may have to change over to LM3406 (due to increased current Requirements…
Other Parts Discussed in Thread: LM3401 , LM3404 I want to run a simulation on the LM3401, 3402, 3404 or 3406 LED driver using a modified reference design (additional components).
I downloaded Orcad Lite & Pspice V16.6 but, unfortunately, the lite version…
Other Parts Discussed in Thread: LM3406 Hi Sir,.
customer got the LM3406 Vin disturbance testing with inductor noise, 3406 switching 130-150KHz
the disturbance source is three each : a. 1-10KHz :Ipp 6, 10KHz-100KHz : 6-5.4log(f/10)*
b. 0.05-1KHz : 0.2Vp…
Hello Peter,
Any part that is chosen for the design needs to be checked for minimum on and off times to make sure it can function over your entire operating range. Switching frequency is also part of that calculation. LM3406 has both minimum on and off…
