Product Details

JW1985 LED Driver IC 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 components and a compact 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 components, which can effectively avoid the problem of EMI. In order to prevent the IC from overheating, the JW1985 integrates a temperature control function. When the temperature inside the chip exceeds TOTP, JW1985 decreases LED current, which can help
chip cooling.
