Description
The DP951X series is a highly integrated constant current LED power switch. The chip adopts a quasi-resonant working mode and does not require an auxiliary winding to detect degaussing. At the same time, it integrates high-voltage 500V power MOSFET and high-voltage self-powered circuit, which simplifies the system design and production costs. The chip integrates high-precision inductor current sampling technology to obtain high Accurate constant current output, and the output line voltage and load regulation rate table DP951X integrates complete protection functions to ensure system safety and reliability
