Build Your Next LED PCB Design in Altium's Unified Environment
LED driver boards can be challenging designs when running at high power and high voltage. Power systems for driving devices like LED panels need careful planning and layout for power supply sections, and the LED PCB itself needs to be laid out to ensure low-temperature operation. These objectives can be difficult to balance without the best set of PCB layout features and DC analysis tools.
When you need to create a high-power LED PCB design, Altium Designer includes the layout and circuit design features you need to create a safe and reliable product. High voltage design features, precise CAD tools, and integrated simulation features give you everything you need to design a safe and reliable LED PCB. Here’s how Altium Designer can help you create LED PCB designs for low and high-power applications.
The only PCB design package with a complete set of layout and simulation features for LED PCB design and manufacturing.
Simple boards with through-hole LEDs are easy to design and don’t carry many special layout requirements. If you need to design something to hand high power output without breaking down during operation, the design process can get very complicated. An LED PCB design can quickly turn into a high voltage system with multiple LEDs, requiring strict power stability and low DC losses in the PDN.
If you want to create a new LED PCB design with high reliability, high power output, and low losses, you’ll need a suite of design tools to ensure success. An integrated design application like Altium Designer can give you all the high power/high voltage design features you need in an easy-to-use interface. When you need to layout, evaluate, and prep your LED circuit board for manufacturing, Altium Designer streamlines the process and helps you get through production quickly.
LED PCBs might be simple systems with small arrays of LEDs, or they may be high-power systems powering a large number of very bright LED arrays. All of these systems need a range of circuitry to ensure stable power delivery to LEDs on the board. Meanwhile, these systems need to be thermally stable; LEDs can dissipate a lot of power during operation, so heat needs to be removed quickly from these systems.
Once you’ve chosen an LED driver IC, designed your power regulation sections, and determined heat management requirements in your PCB layout, you’ll need to capture your board in a blank PCB and start laying out components. Your PCB layout will be a major determinant of reliability, and designers need a complete set of PCB layout tools to prevent board failure.
Your LED PCB Layout Determines Reliability
Your layout is partially responsible for removing heat from your LED while also ensuring stable power delivery. With the right set of PCB layout tools, you can take major steps to ensure reliability in your LED PCB. With the industry’s best CAD tools, you can easily place and arrange components in the board while also routing and pouring copper to help dissipate heat from critical components. Keeping your components cool and providing stable DC power will help ensure your board remains reliable during operation.
- Removing heat is a top priority in LED PCB designs. LED driver ICs need to be kept cool to prevent shutdown, and LEDs need to be kept cool for heat dissipation.
- Copper is key to moving power around an LED PCB and to ensuring heat can be removed from critical components.
- LED driver boards can be simple to design when you have the best set of PCB layout features at your fingertips.
You can build this type of high-power LED PCB design with Altium Designer’s complete set of circuit board layout and manufacturing tools.
If your LED PCB design will run at high power, then you may need to design a highly stable regulator to provide stable DC power to your LEDs. Power systems for LED PCBs must provide the required DC power output in a compact package and without overheating. LED driver ICs can shut down if overpowered or when their temperature gets too high. Designers need to balance multiple requirements to ensure reliability and safety.
There are many sub-systems you might need to place into your LED PCB design to ensure stable power and reliability. These might include:
- Rectifier, filter, and PFC circuits to receive and convert AC power
- Regulator circuits to convert and stability DC power
- LED driver circuitry to provide dimming and power control
- A feedback control loop to ensure stable output against power dropout
Designing these sub-systems takes circuit simulation features, PCB layout features, and integrated post-layout simulation tools to examine power stability and temperature rise. Altium Designer gives you access to a range of simulation features for high voltage and high current design, including for LED PCB designs.
Power Simulations You Can Perform in Altium Designer
The circuit design tools in Altium Designer include an integrated SPICE simulator for examining electrical behavior in all portions of your LED PCB. Once you’ve captured your schematics and created your PCB layout, you can use a PDN analyzer extension to simulate DC losses on your PDN and determine where power dissipation will be greatest. Once you identify hot spots in your board, you can use Altium Designer’s powerful CAD tools to make corrections to your board without huge redesigns. Everything you need for LED PCB design and much more can be found in Altium Designer.
- Higher power LED systems often need an LLC resonant converter with PFC circuit to convert AC power to DC with high efficiency.
- After creating power converter schematics, a design should be simulated to ensure it produces desired power output and ripple before creating a PCB layout.
- Altium’s best-in-class simulation tools make PDN analysis and simulation extremely easy, including electrical-thermal co-analysis for LED PCB layouts.
