The CH32V003 series is an industrial-grade general-purpose microcontroller based on the Qingke RISC-V2A core. It supports a 48MHz system clock frequency and features wide voltage range, single-wire debugging, low power consumption, and an ultra-small package. It provides commonly used peripheral functions, including one DMA controller, one 10-bit analog-to-digital converter (ADC), one operational amplifier comparator, multiple timers, and standard communication interfaces such as USART, I2C, and SPI. The product has a rated operating voltage of 3.3V or 5V and an operating temperature range of -40℃ to 85℃ (industrial grade).

The BP3286J is a high-efficiency, high-PF LED driver chip that supports SCR dimming. Operating in inductor current critical continuous mode, it is suitable for Buck-Boost LED driver power supplies. The BP3286J integrates a 600V power switch and employs a patented gate drive and high-voltage power supply method, requiring very few external components to achieve excellent constant current characteristics, significantly reducing system cost and size. The BP3286J features multiple protection functions, including LED open-circuit protection (overvoltage protection), LED short-circuit protection, and chip temperature overheating regulation. The BP3286J is packaged in an SOP-8 package.
