Additional preview pages of the JW1779 datasheet.

JW1779 is a non-isolated, constant output current step-down LED driver with 500V MOSFET integrated. Operating in the boundary mode makes it high efficiency and low radiation. Patented algorithms ensure good current accuracy and excellent line/load regulations with lowest BOM cost. JW1779 is supplied from the MOSFET drain directly, so the auxiliary winding is eliminated, which can light up the LED within 100mS. With unique sampling techniques, JW1779 has multi-protection functions which can larg.
