Default My boost driver not boosting?

Hey guys so I finish my first 445nm driver base on tps611650
When I hook up the 445 diode to the driver nothing happen so I measure the Vout of the driver. I got the 3.9v reading while my battery is 4.0v (WTF? the driver is bucking?) So I hook the 650 diode to the driver instead and it seem to work fine. It output a stable 300mA and when I change the sense resistor the current change seem to match the calculation from the data sheet.



My set up is exactly the same as above except I change the input and output cap into 10uf. If anyone can tell me what I am doing wrong it will be greatly appreciated.

Default Re: My boost driver not boosting?

At 350mA the 445s are taking around 4V iirc. Decrease yor battery voltage...
What is a 650 diode? The red LOC or LCC types need even less voltage (2.6/2.7V) at 350mA. So something is wrong here...

Default Re: My boost driver not boosting?

Yes at 300mA that is what it should be outputting so your driver worked fine if you turn it up past 600mA then you will see it start to boost I am pretty sure

I am using a dead ML101J26 from Mitsubishi as a test load. Just curious what do you mean by LOC / LCC? Isn't that only a infra red diode have a 2.6/2.7V voltage drop?

I really won't consider my boost driver is worked fine since I can never get a output voltage higher then the input voltage. I have even replaced the inductor value from 10uH to 100uH. I even remove the inductor and simply bridge the pad and the driver is still working with the same result.....

The one thing that I find very strange is the driver will give a >8v no load voltage at the moment I hook the battery but then drop and remina stable on 3.98v. Is there any kind of limit on the IC? What am I doing wrong?

Well it depends what the diode is pulling from the driver. With the info you've provided this is what I could help you with. If you can provide some pictures of your board then that may help me help you

Default Re: My boost driver not boosting?

Why would it boost for a red diode?

The driver will make the output voltage whatever it needs to be for the diode to draw the set current. If you want it to boost use a proper load.

His ic is a buck-boost so it's running the red diode in buck mode


But also why would you need to boost for a red diode????

The IC is boost only, not boost-buck.

Not sure what you are trying to say
You attempted to answer my (rhetorical) question, then asked it again.

Ok I apologize I thought he was using this ic TPS63020 not the TPS611650. This is a boost only ic but I got mixed up for a second there. But then it's up to him to answer the question why he is using this for a red

Did you take ESD precautions? These ICs need to be handled carefully. You could have damaged it. I have been there before. Once the opamps or fets are blown, these devices start to behave funny...

What do you have CTRL hooked up to?
You schematic shows 5v, But you mention a battery,
what battery are you using

Got a pic of your setup?

Also what are you using as D1?

I am not building this driver for red diode. Just because I saw the output voltage is 3.98v only so I try it with my red diode.

I still cannot draw more current from this driver. Is this IC supposed to provide 1.2A for a 445nm diode? Even if the efficiency is calculated I still should get around 800mA-900mA but not 300mA only. Any recommendation?

I only request one sample from TI. I cannot tell whether this is a defected unit but from what I see the IC should working maybe the value of some outside component is wrong.

Sorry my DC is down for some reason and so I cannot upload the picture of the driver just the moment. I leave the CTRL pin empty and I am using a 18650 for the test.

No, It has a 1.2A Switch
Roughly meaing:

you can take in 1.2A from your 4V battery
Giving 4.8W in
-efficency

So with a 445 .7A mabye

Check your datasheet,
but Im pretty sure you need to hook up CTRL to Vin
