The price may be the seller’s own price elsewhere or another seller’s price. You still do not have the required current limiting for the LEDs in place, you added L1 but it is useless here. This means that, for a load current of 1 amp, you’ll need about mA of base current, which should be well transisror the capabilities of a Trey Carpenter 6 2.

See details for additional description. This item doesn’t belong on this page.

Actually, from the data sheet, at 1 amp collector current, a mA base drive will only drop your Vce to 5 volts using the C, so I don’t recommend using it. What you may measure is the average Vce.


Home Questions Tags Users Unanswered. WhatRoughBeast 49k 2 28 Bad, bad circuit it seems. You must choose at what current you want to operate them, make an estimate of the voltage usually around 2. Take a look at this: I’ll disagree with Andy about your filtering.

I have been working on a high-powered LED light bar. If the voltage is more than 1 volt, you know you’re trying to pull more than an amp. I have considered and addressed your comment in the one above.

It is basic electronics knowledge. You think you control Vce by changing R2 but you’re not. You must not treat a string of LEDs as having a resistance! For high power LED drivers like this you really must know what you’re doing.

Your problem is most likely that you are not able to provide enough base current to turn the transistor fully on. Be the first to write a review. You may also like.

Cc3866 I know the circuit works. No ratings or reviews yet. Same for D0, not needed. I believe that your cap is adequate. What you need to learn first cannot be explained here in a transstor lines. Do this by replacing the trannsistor with a 1 ohm, 2 watt resistor, and check the voltage across it. I’d recommend that you double-check the LED current. Furthermore, the Vbe will be about 0.

So the resistor should be about 10 ohms.
