Hi Bogey,
What's your application? Do you really need 350mA/channel? We don't have a device that very match MP3398. If you don't need such high output current , may be TPS61194,TPS61177A,TPS61187 is good. If you really need such high cureent, Maybe…
Hello,
The LM3466 was designed to balance current between multiple LM3466s, for example, if a one amp current source drives two 500 mA LED stacks the two LM3466 would balance the current between the stacks even if they have different forward voltage…
I would need to know what input voltage range is used and whether PWM or analog dimming is required. But one route is the LM3464. It will control 4 strings and work with nearly any other regulator. For an example you can check out http://www.ti.com/tool…
Thanks, I powered the LM5021-1 with 7.15V and was able to get switching at the frequency I desired (100KHz) and sorry I didn't send the correct schematic in last message. I've attached a power point with the current circuit and plots, LM5021-1 reguation…
Hello,
I would not recommend using the LM3466 across ten boards as a current sharing device. They are trying to share current from a single current source to multiple LED strings. If you want to try this I would place all LM3466s on the same board…
I can think of two approaches of this high power application.
1. As Michael mentioned above, you can use LM3463(6channels output with 4 channels individual PWM dimming) or LM3464(4 channels output and each can do PWM dimming). Both parts uses linear…
Hi Roland,
To regulate seven/eight strings you would need seven different voltage sources if a linear was regulating each string for efficiency reasons. If one supply is used the same problem exists, the highest stack determines the voltage to all…
Other Parts Discussed in Thread: TL4242 , LM3466 , LM3464 Hi!
I have an external 350mA LED driver module (Vossloh-Schwabe ECXe 2350.037). I would like to use this module to drive 6×6 Seoul 5630 LED (100mA@3.2V). So basically, there are 6 strings of…
Other Parts Discussed in Thread: LM3464 I'm looking to do a design with 16 high brightness LED controlled independently. Each LED is 8A @ 4v, and I have a 24v supply. Anyone have any recommendations for this? I'm looking at the LM3434 as a potential solution…
Hi,
i am buying one EV SR#1-1023927256 / LM3464-120V24W/NOPB working with 110 V ac EV led driver board which is designed for ac/dc isolated with dc/dc converter for 24w led . i want convert this EV board for working with 230v ac . i want to know the…
