JW1985 Datasheet | JoulWatt Technology

DESCRIPTION JW1985 is an ultra-high-voltage 3-string 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 ponents and pact layout, and can be easily and flexibly applied to various small-size or flat LED products. JW1985 greatly improved the power factor and THD of the system (meeting the IEC61000-3-2 standard). At the same time, the simple linear drive method does not require magnetic ponents, which can effectively avoid the problem of EMI. In order to prevent the IC from overheating, the JW1985 integrates temperature control function. When temperature inside chip exceeds TOTP, JW1985 deceases LED current, which can help chip cooling. pany’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of Joulwatt Technology Co., Ltd.
