Integrated 500V MOS Non-isolated
Buck LED Driver
DESCRIPTION
FEATURES
JW1782B 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.
JW1782B 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, JW1782B has
multi-protection functions which can largely
enhance the safety and reliability of the system,
including VDD UVLO, inductor short protection,
LED short protection and over-temperature
protection.
