JW1983 Ultra-high voltage Linear LED Driver Parameters Subject to Change Without Notice DESCRIPTION JW®1983 is an ultra-high-voltage linear constant-power LED driver with a maximum input voltage of 700V, which is suitable for driving high-voltage low-current LED loads. The application solution has very few external components and compact layout, and can be easily and flexibly applied to various small-size or flat LED products. JW1983 can provide 5 ~ 150mA constant current. JW1983 integrated Multiplier, greatly improved the power factor and ultra-low THD of the system (meeting the highest IEC standard). At the same time, the simple linear drive method does not require magnetic components, which can effectively avoid the problem of EMI interference.
