Default FS - rkcstr 405nm boost drive

i have two 405nm boost drivers custom made for me by rkcstr

3cm by 1cm (not including spring)

input 3v and the output is 4.5v, fully adjustable

http://rkcstr.googlepages.com/BoostD...structions.doc

you will need to be careful with these drivers, as the diode heats up the power will increase slightly. so you need to set the power lower to allow for the increase.

i believe i paid $25 for both, so i will be asking for the same amount

Default Re: FS - rkcstr 405nm boost drive

These were from a project I started earlier this year. *I thought about selling them, but they're not exactly ideal and require some playing around to get it set properly. *They're voltage regulating at 5.0V output with a series variable resistor (pot) on the output to the laser diode (20ohm max) to limit the current. *They can, however, run on a 1.5V battery at low currents. *The output will get dim when the voltage isn't high enough to regulate, so don't freak out thinking you blew the diode!

The driver was originally designed for powering the PS3 diodes (KES-400A sleds) in a DX green pointer case, so the pot was to limit the current down to about 30-40mA, but the chip is capable of putting out around 200mA if you provide sufficient input voltage (typically &gt;3.0V). *However, the current setting is NOT regulated, so as the diode gets warm, the current will increase. *This means you need to set the current LOW, to account for the rise with time (actually temp). *Its not so big of a deal for the 803T diodes, since they're forgiving with current, but you should still watch to make sure it doesn't get TOO high.

My recommendation: *measure current from the start, then allow it to drive the diode and keep an eye on the current with time and make sure it doesn't go above your limit, if it gets close, turn the pot counter-clockwise a little (increase resistance).

Datasheet for the IC, figures 5 and 8 give details on the input voltage/output current:

Some quick instructions I made up a while ago, not very thorough:

The diode needs 5V. The old Rkcstr driver needed 2.2V itself. You needed 7.2V to power BOTH the diode AND the driver.

This boost driver puts 5V to the diode.

7v.. actually about 7.25v is the lowest input voltage for a regular rkcstr driver running a BR diode. The diode itself at lower currents needs 5v. Raise the current and it needs ~6v depending on how high you go. For higher currents the regular driver will need 8v or more.

A boost driver will take a lower source voltage, and raise it to what the diode needs. The cost of this is usually added current draw to the battery to make up for the voltage jump. One thing to remember with a boost driver is to NOT measure the current at the battery, since the diode itself will be being fed a lower current, depending on the voltage it is &quot;taking&quot;.

the input for this driver is 3v and it will output 5v for a blu-ray diode
