DESCRIPTION
BW7383 is a non-isolation Buck type control IC
with active power factor correction function for LED
lighting application.
The IC achieves high power factor and high
efficiency by BCM mode. The line and load
regulation of LED current is about ±2.5% because
of particular control method.
BW7383 also provides gate driving voltage
clamping, VCC over voltage protection and system
output open/short circuit protection to increase IC
performance.
APPLICATIONS
LED lighting
Down light
Tube lamp
PAR lamp
Bulb
