# Picobuck Led Driver (AL8805W5) ## Description (AL8805W5) The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board, allowing it to be used up to the full 36V rating of the AL8805 part. ## Project Details - **Owner:** adrian95 - **Created:** 1/31/2022 - **Last Updated:** 2/17/2022 - **Visibility:** Public - **Stars:** 2 ## Key Components ### D1 — [MBRA140T3G](https://www.flux.ai/adrian95/mbra140t3g.md) - Manufacturer Part Number: MBRA140T3G - Manufacturer Name: ON Semiconductor - Part Type: Diode - Datasheet URL: https://www.onsemi.com/pdf/datasheet/mbra140t3-d.pdf **Pins:** - ANODE - CATHODE ### D2 — [MBRA140T3G](https://www.flux.ai/adrian95/mbra140t3g.md) - Manufacturer Part Number: MBRA140T3G - Manufacturer Name: ON Semiconductor - Datasheet URL: https://www.onsemi.com/pdf/datasheet/mbra140t3-d.pdf - Part Type: Diode **Pins:** - ANODE - CATHODE ### D3 — [MBRA140T3G](https://www.flux.ai/adrian95/mbra140t3g.md) - Manufacturer Part Number: MBRA140T3G - Manufacturer Name: ON Semiconductor - Part Type: Diode - Datasheet URL: https://www.onsemi.com/pdf/datasheet/mbra140t3-d.pdf **Pins:** - ANODE - CATHODE ### J1 — [OSTTF020161](https://www.flux.ai/adrian95/osttf020161.md) - Manufacturer Name: Texas Instruments Inc. - Manufacturer Part Number: OSTTF020161 - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/On%20Shore%20PDFs/OSTTFXX0161_Dwg.pdf - Part Type: Connector **Pins:** - 1 - 2 ### J2 — [OSTTF020161](https://www.flux.ai/adrian95/osttf020161.md) - Part Type: Connector - Manufacturer Part Number: OSTTF020161 - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/On%20Shore%20PDFs/OSTTFXX0161_Dwg.pdf - Manufacturer Name: Texas Instruments Inc. **Pins:** - 1 - 2 ### J3 — [1725656](https://www.flux.ai/adrian95/1725656v2.md) - Manufacturer Name: Texas Instruments Inc. - Datasheet URL: https://www.snapeda.com/parts/1725656/Phoenix%20Contact/datasheet/ - Part Type: Connector - Manufacturer Part Number: 1725656 **Pins:** - 1 - 2 ### J4 — [OSTTF020161](https://www.flux.ai/adrian95/osttf020161.md) - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/On%20Shore%20PDFs/OSTTFXX0161_Dwg.pdf - Manufacturer Part Number: OSTTF020161 - Manufacturer Name: Texas Instruments Inc. - Part Type: Connector **Pins:** - 1 - 2 ### J5 — [OSTTF020161](https://www.flux.ai/adrian95/osttf020161.md) - Part Type: Connector - Manufacturer Name: Texas Instruments Inc. - Manufacturer Part Number: OSTTF020161 - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/On%20Shore%20PDFs/OSTTFXX0161_Dwg.pdf **Pins:** - 1 - 2 ### J6 — [1725656](https://www.flux.ai/adrian95/1725656v2.md) - Part Type: Connector - Manufacturer Part Number: 1725656 - Manufacturer Name: Texas Instruments Inc. - Datasheet URL: https://www.snapeda.com/parts/1725656/Phoenix%20Contact/datasheet/ **Pins:** - 1 - 2 ### JP1 — [Solder Jumper 2 Open](https://www.flux.ai/adrian95/solder-jumper-2-open.md) - Manufacturer Part Number: Jumper_2_Open **Pins:** - A - B ### JP2 — [Solder Jumper 2 Open](https://www.flux.ai/adrian95/solder-jumper-2-open.md) - Manufacturer Part Number: Jumper_2_Open **Pins:** - A - B ### JP3 — [Solder Jumper 2 Open](https://www.flux.ai/adrian95/solder-jumper-2-open.md) - Manufacturer Part Number: Jumper_2_Open **Pins:** - A - B ### U1 — [AL8805W5-7](https://www.flux.ai/adrian95/al8805w5-7.md) - Part Type: LED - Manufacturer Name: DIODES INC. - Datasheet URL: https://www.farnell.com/datasheets/2100145.pdf - Manufacturer Part Number: AL8805W5-7 **Pins:** - CTRL - GND - SET - SW - VIN ### U2 — [AL8805W5-7](https://www.flux.ai/adrian95/al8805w5-7.md) - Datasheet URL: https://www.farnell.com/datasheets/2100145.pdf - Manufacturer Part Number: AL8805W5-7 - Manufacturer Name: DIODES INC. - Part Type: LED **Pins:** - CTRL - GND - SET - SW - VIN ### U3 — [AL8805W5-7](https://www.flux.ai/adrian95/al8805w5-7.md) - Datasheet URL: https://www.farnell.com/datasheets/2100145.pdf - Manufacturer Part Number: AL8805W5-7 - Manufacturer Name: DIODES INC. - Part Type: LED **Pins:** - CTRL - GND - SET - SW - VIN *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/adrian95/picobuck-led-driver-al8805w5](https://www.flux.ai/adrian95/picobuck-led-driver-al8805w5).* --- *Generated from [https://www.flux.ai/adrian95/picobuck-led-driver-al8805w5](https://www.flux.ai/adrian95/picobuck-led-driver-al8805w5)*
