The led has it's anodes to the top of the board (near the 10w rgb led driver silkscreen) and the cathodes along the bottom (near the robg silkscreen). Guangzhou mankun electronic co., ltd. I know there's some confusion about my 10w rgb led driver (later called 10wld,) so i will try to explain how it works in this thread.
10pcs/lot PT4115 SOT 89 5 Driver IC / buck converter / LED
The board will fit into a standard 10w flood light enclosure.
However, i used beefier components and a different chip.
This driver was designed to drive 10w rgb led modules (led is not included in the kit) using dumb led controllers. I want to use my arduino to control a 10w rgb led using pt4115 driver. I built a led driver with pt4115 ic. 22uf tantalum capacitors (digikey part number:
I have to connect each color to separate drivers (obviously 3 pt4115 drivers is needed).
Light driver controller, speedless capacitive tuner sjt83. Since each driver has a 2 pins for each led. 50 watt led driver circuit diagram. I use 3 pwm pin of the arduino to control the led.
68uh power inductor, 0.7a (digikey part number:
The drawing is a wiring diagram, not a circuit schematic, and this it is indeed rather hard to follow.and while i may guess that the pt4115 is some sort of led driver device i am not going to do a search to see how it should work. Mini thermal receipt printer, serial 5v [type] 5.00 out of 5. Id name designator footprint quantity; Offers flexible prices for led driver variations depending on the importing country and quantity.
The price of adjustable current pwm led dimmer pt4115 led driver ic dc36v 900ma 30w or dc24v 500ma 12w buck converter led driver from china is based on the bulk order quantity.
I removed r2, d2 and r3 so the dim pin is floating. 1 customer review | add a review. Also it is a wise choice to state what the circuit is intended to do. Ahmadx87 november 25, 2016, 6:38pm #1.
Soldering sequence this is a pretty simple board with only a few components.
However, if you do nothing else, solder the pt4115 ic's first. Below is the schematic and the pcb board: Can be powered from 12v to 24v supply. Led display driver, printer tags:

The device is powered by a 6v to 30v input source and has a 1.2a output current that may be adjusted externally.the pt4115 may produce more than. Show activity on this post. Driving common anode rgb led with pt4115. The board lighted leds up but sparks appeared around sw, vin & gnd pins after 10 seconds and the phenomenon didn't damage the ic.
Schottky diode 2a sma package (digikey part number:
I recorded it by my mobile phone. It has a pwm input for light dimming and is mainly used for led driving.
