JW19836 Datasheet | JoulWatt Technology

DESCRIPTION JW®19836 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 few external ponents and pact layout, and can be easily and flexibly applied to various small-size or flat LED products. JW19836 can provide 5 ~ 150m A constant current. JW19836 integrates a multiplier, greatly improved the power factor and THD of the system (meeting the highest IEC standard). At the same time, the simple linear drive method does not require magnetic ponents, which can effectively avoid the problem of EMI interference. JW19836 adopts closed-loop control method to achieve constant output current control, and has excellent line and load regulation within a certain input voltage range. JW19836 also monitors the line voltage in real time to achieve the effect of inputting constant power. pany’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of Joul Watt technology Inc. TYPICAL APPLICATION Ultra-high Voltage Linear LED Driver When the internal junction temperature of the IC rises to 135°C, the JW19836 starts to reduce the output current.
