Breakout Board for TLC5947 LED Driver or other 32-Pin HTSSOP and TSSOP Package

$7.00 – $19.00

This is a breakout board for the TI TLC5947 IC, a constant-current LED driver supporting 24 channels and 12-bit PWM control per channel. Unfortunately, this powerful yet easy-to-drive IC is only available in high-density packages that are hard to solder without special equipment and skill. Even more so considering that the TSSOP package not only features a 0.65mm pitch but also requires an integrated heat sink underneath — this is what TI calls a DAP/PowerPAD Thermally Enhanced package. That means that there is a thermal pad at the bottom side of this HTSSOP package that needs to be connected (i.e., soldered) to a heat sink (i.e., two or more copper planes connected through thermal vias) integrated (i.e., designed) into the PCB.

Features

  • breakout board for TI TLC5947 constant-current LED driver
  • supporting 24 channels and 12-bit PWM control per channel
  • heat sink integrated in PCB using thermal vias
  • available with TLC5947 IC soldered on
  • available with R1 preconfigured for 15, 20mA constant current
  • also available as a plain item without any components soldered on for use with any other TSSOP IC (up to 32 pins) in a 0.65mm pitch
  • standard 2.54mm (100 mils) pitch, narrow size, making this board very suitable for use on a breadboard
  • size: 22.86×43.18mm
  • high-quality PCBs designed in KiCad and produced by Aisler (Germany), PCBWay (China), and OSH Park (USA)

Usage

  • This board has a TLC5947 IC soldered on and a plain, empty item that can break out any other TSSOP IC (up to 32 pins) in a 0.65mm pitch.
  • This breakout board’s standard 2.54mm (100 mils) pitch and narrow size make it suitable for use on a breadboard.
  • I have used this board to drive 16-segment LED displays when developing a display and effect library for this type of element in C for AVR8.
  • For people willing to create their design using the TLC5947 IC, a footprint for KiCad is available here.

Shipping Policy

FAST DELIVERY! We ship worldwide via FedEx, UPS, DHL, and USPS because they’re Fast, Reliable, Affordable, and Easily Trackable. We process orders in 24 hours; delivery may take 4 to 7 days or sooner, depending on your location. Once shipped, you will receive an email with your tracking number.

Ships From: Not all our products are shipped from the USA; some are from different countries and regions like China, Taiwan, or Europe. Therefore, the amount of tariff you will pay will differ depending on which country your order will be shipped from. This is to keep tariffs as low as possible, because not all countries charge the same amount. For example, if the US imposes a tariff of 30% on goods from China, other countries will impose a much lower tariff on products shipped from China. Please check the "Ships From:" label on this product to see which country it will be shipped from.

TARIFF: The tariff will only affect customers in the country where they reside and order. Please check the "Ships From:" label on this product page to see which country we will ship this product from. While not all products require a tariff, some may require a minimal or no tariff in your country. If applicable, the buyer will pay the tariff within their respective country. The total amount of your order does not include a tariff. Please enter a reachable phone number during checkout so the Shipping Company can contact you to pay the tariff once your parcel arrives at your destination.

Why don't we add tariffs to the product's retail price? If all countries imposed the same tariff amount and used the same currency, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount and uses a different currency, while some do not even charge a tariff. Therefore, we can't add a tariff to the product's retail pricing. Oz Robotics' manufacturing partners, or suppliers are not responsible for tariffs. Please check the "Ships From:" label on the product page to see the product's origin. The total amount for your order does not include a tariff. The customer must pay the tariff. We will not cancel your order or refund you if you do not pay the tariff. More Details.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity. For lower shipping costs for orders with multiple items, please email us at sales@ozrobotics.com before you buy. We show shipping rates on the product page under the SHIPPING tab. To see the shipping cost for your country, click add to cart on the product page.

PRODUCT DATASHEET AND MANUAL: If applicable, the Product Documentation, such as the Datasheet, CAD Design, STP Files, Manuals, Reference Materials, and Tutorials, will be available for download upon purchase from the My Account as needed.
