تراشه LED درایور DP9503B پکیج SO-7

Description

The DP950XB series is a highly integrated constant current LED power switch. The chip adopts a quasi-resonant working mode and does not require auxiliary winding detection and degaussing. At the same time, the high-voltage 500V power MOSFET and high-voltage self-powered circuit are integrated internally, which simplifies the system design and production costs. The chip integrates high-precision inductor current sampling technology to obtain high-precision constant current output, and the output line voltage and load regulation rate are excellent.
