It meets the needs of various applications and end markets for automotive interior lighting decoration, indoor lighting atmosphere scene applications, and toy lighting.
In modern intelligent lighting products, lighting is not only to satisfy people's visual light and dark effects, but also to have a variety of control schemes to make the lighting of the house more artistic and let people enjoy the beautiful visual effects. Based on the Microchip MCP19xxx series, Beineng International provides an ambient light solution. The solution uses a highly integrated PIC MCU core to achieve dynamic adjustment. While saving costs for users, it also effectively improves the accuracy, energy efficiency and light quality of LED lighting. It meets the needs of various applications and end markets for automotive interior lighting decoration, indoor lighting atmosphere scene applications, and to lighting.
The solution chooses Microchip's MCP19xxx as the MCU, the single-chip MCP19xxx realizes power management, controls RGB through I2C communication, and realizes color and single lamp bead control to help improve the accuracy of LED lighting, so that users do not sacrifice light color or light quality at the expense Precisely control the output intensity of LED light to achieve reliable and durable applications.
Using SEPIC topology, constant voltage output
UART interface is reserved for external control
Through I2C communication, the LED is controlled by a dedicated chip, and the state of a certain LED lamp bead can be individually controlled to achieve more display methods
Input voltage: 5~16Vdc
Maximum output power: 5W (more power can be output by changing the power device)
Output load: 12/24 RGB lamp beads .
