Yesterday evening (CET) I’ve built my newest DC-DC converter with the LT chip from Linear Technology with a hand drawn and etched pc.

Here some additional results: I will soon make more tests with different numbers of LEDs. In this case you could compare the above published results with your configuration with two chains of LEDs in parallel. Pricing displayed for Evaluation Boards and Kits is based on 1-piece pricing. It is important to note the scheduled dock date on the order entry screen.

It would need an additional switch or a pot or whatever else which makes a flashlight mod much more complicated. If you use nimh batteries it won’t be as bright, or if you set it up for full brightness with nimh batteries it will overload with regular batteries.

But I think first I’ll do some more tests and as my time to work on this project is limited the mods have to wait. The only thing missing was the overall size of the board, which you filled in in the last post above.

We do take orders for items that are not in stock, so delivery may be scheduled at a future date. Maybe it would be better to have both chains on all the time, and just vary the current output for a dimming function. Now to order some parts and do something with them.

What is the minimum current the LT can regulate?

Front Page What’s New? I will do some more tests to learn more about it and then poosibly try to improve it a bit. Model Package Pins Temp. Price Rohs Orders from Analog Devices. I couldn’t make a lot of tests up to now but here some first results: If you drive your LEDs on 4. IMO there a kt1932 lot of better chips to drive the LS eg. I don’t know wether 3 AAA l1932 in series will be able to deliver the necessary input current. Right now, I’m on another project, so I’ll be unable to build this for a few weeks yet.

This is the acceptable operating range of the device. What’s your next step?

International prices may differ due to local duties, taxes, fees and exchange rates. LTspice downloads and documentation. Maybe this is caused by the higher DCR 0.

Two in series doubles the ability of the string to handle ripple voltage, three in series triples, etc. Do you have enough components to do a test run for me? Lt132 achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. With this booster, a string of 5 Nichias in series, an input voltage of 2. With 3 volts input the situation looks much better. I will post these results later on. I tl1932 why the voltage regulators don’t ly1932 higher output voltage and the chips like LT don’t regulate?

That’s why I mentioned the to mA to Wayne. Keep in mind a low ESR cap draws more current then a non ESR cap when charging up, which in some apps can actually cause a drop in efficiency.

In the low input voltage range the output current drops very fast. I started the test at 6: Unfortunatly I didn’t find out up to now how to remove the battery case without destroying the housing. Ok, there is not much to say about it. With a string of Nichias in series, the situation is even better. Indicates the packing option of the model Tube, Reel, Tray, etc. You would have to add some hours more because in this time the Nichias sucked much more energy out of the batteries because of the higher current.

Do you think it llt1932 drive a Luxeon? Please enter samples into your cart to check sample availability. Looks like you’ve got a buildable design. Please consult the datasheet for more information. I am thinking of a round design, so as to use it in a round flashlight.
