REF_ICL8800_LED_43W This 43 W reference design uses Infineon's high power factor flyback controller ICL8800. The evaluation board is a constant voltage (CV) secondary side regulation (SSR) system designed for use with a constant current (CC) converter for LED lighting applications. Two-stage topologies are becoming increasingly popular due to the easy scalability of primary-side power and secondary-side characteristics. The REF_ICL8800_LED_43W solution features a plug-and-play design and can be used with the secondary-side DC/DC evaluation board. As a default, the reference design board is equipped with a depletion mode MOSFET BSS126I based startup circuit on a small adapter board. This setup will significantly reduce standby losses. If low standby power consumption is not required, the startup circuit can be changed to a resistive startup design. This reference design comes with two conditioning circuits. Both are plug-and-play solutions, but at least one circuit must be connected to the motherboard. There is a cost trade-off between the two evaluation boards; the TL431 evaluation board is lower cost and has good standby performance, while the op amp board exhibits excellent overall performance at the 30 mW power level.
Want to add lots of LEDs to your Arduino project? HUB75 RGB panels are a great way to do this as they are much cheaper than addressable Neopixel/WS2812 LEDs (typically 10% of the cost per LED). They are also available in a range of pixel densities (from 2mm to 10mm pitch) to better suit your project needs. However, using a microcontroller to display high-quality graphics on a HUB75 panel is complicated because the panel requires precise timing and constant refreshing of pixel data. That's where Teensy 4's SmartLED Shield comes in.
