JW1967DD
product description
JW®1967A/ JW1967B/ JW1967C/ JW1967D/JW1967E/ JW1967EH (JW1967X series) is a high-precision LED driver, mainly used in single-stage, non-isolated step-down LED driver systems with source PFC.
The JW1967X series integrates a high-voltage current source, directly powered by the bus voltage, without auxiliary windings and VCC capacitors.
Patented current detection and digital compensation technology can ensure excellent power factor and high-precision output current control. The inductor current works in critical continuous mode, which reduces the switching loss of power devices and ensures high efficiency of the system.
The JW1967X series integrates a variety of protection functions, which greatly enhance the safety and reliability of the system, such as LED open circuit protection, LED short circuit protection, over temperature protection, etc.
