Do you wish to management the color, depth and temperature of the lightning utilizing simply your cellular? Then look no additional as on this article we shall be studying extra a few reference design from Microchip, that lets you management totally different parameters of LED strip utilizing only a cell phone.
The color and temperature of lightning impression the atmosphere of an surroundings. The proper lighting can enhance our productiveness, and temper and in the long term may even impression our general well being. However it’s not sensible to have a number of lights put in, and the development of LED applied sciences has allowed designers to manage the depth of sunshine by controlling the voltage.
This reference design from Microchip can permit prospects to drive two totally different color LED strips, it could permit the customers to manage the temperature, color and depth of sunshine. The reference design permits the person to manage the settings by means of Bluetooth communication, it makes use of RN4871 Bluetooth Low Power (BLE) module which integrates Bluetooth 4.2 baseband controller, on-board Bluetooth stack, digital and analog I/O, and RF energy amplifier into one answer.
The reference design employs a buck LED driver and an 8-bit PIC microcontroller to create an clever LED lighting system answer. The reference design takes an AC enter from 50 to 265VAC. The picture under present the answer diagram of the reference design.

Reference Design Key Options:
• Common Enter voltage: 120/230 VAC 50-60Hz
• Transformerless: reduces BOM value and undertaking dimension.
• Passive Energy Issue Correction: it gives a PFC of no less than 0.9 at 120Vac and 0.85 at 230Vac.
• RN4871 Bluetooth Low Power 4.2 baseband controller: on-board Bluetooth stack, digital and analog I/O, and RF energy amplifier into one answer.
• Dimming and temperature color adjustment: by combining a fundamental buck LED driver (HV9961) that includes an 8-bit PIC16F15313 microcontroller.
• Person pleasant: this undertaking comes with a Cell Utility for Android.
• The microcontroller and the BLE module is provided offline utilizing DN2470 (D-FET).
Design Sources
Microchip has validated this reference design and has additionally offered all the required design sources such because the BoM, Gerber file, schematics, software program recordsdata, and so forth. to simplify the event of this reference design. It’s worthwhile to signal as much as entry the design recordsdata, you will get all of the design sources right here.
