DP95030T
product description
The DP950XT series is a highly integrated constant current LED power switch. The chip adopts a quasi-resonant working mode without auxiliary winding detection and demagnetization. At the same time, a high-voltage 500V power MOSFET and a high-voltage self-powered circuit are integrated internally, which simplifies the design and production cost of the system. The chip integrates high-precision inductor current sampling technology to obtain high-precision constant current output, and the output line voltage and load adjustment rate are excellent, and the OTP protection point can be adjusted by external resistors.
DP950XT integrates complete protection functions to ensure the safe and reliable operation of the system, such as: VDD under-voltage protection (UVLO), cycle-by-cycle current limit (OCP), over-temperature protection (OTP), CS sampling resistor short-circuit protection, LED short-circuit protection, etc. .
