WS344X is the most advanced LED constant current control chip for non-isolated applications
The step-down LED power supply system is suitable for a full range of AC voltage input or DC voltage input of 12V~500V.
The WS344X has an integrated 500V power MOSFETs and requires very few peripheral components to achieve excellent constant current characteristics.
The WS344X chip has the best current sampling circuit, and adopts the best constant current control technology to achieve the best LED constant current output and excellent linear adjustment rate. The chip works in the inductive current critical mode, and the system output current does not change with the inductance and the operating voltage of the LED, achieving excellent load adjustment rate.
WS344X adopts the most advanced source drive technology, the chip operating current is only 200uA, no auxiliary winding power supply, simplify the design, reduce the system cost.
The WS344X uses the most intelligent temperature control inside, which can easily solve the problem of light flashing when high temperature.
The WS344X features multiple protection features, including LED open\/short circuit protection, current sampling resistance short circuit protection and chip overtemperature protection.
