DESCRIPTION
JW
®
1763M/A/B/C/D is a constant current LED
regulator with high output current accuracy which
applies to single stage step-down LED drivers.
High voltage power MOSFET is integrated, which
can significantly simplify the driver system.
High precision constant current control ensures
high accuracy of output current. Critical
conduction mode operation reduces the switching
loss and significantly increases the efficiency,
also reduces the electromagnetic interference.
JW1763M/A/B/C/D can be supplied from the bus
voltage directly, and auxiliary winding is not
needed.
JW1763M/A/B/C/D has multi-protection functions
which largely enhance the safely and reliability of
the system, including LED short-circuit protection,
LED
open
protection and
over-temperature
