ORDER INFORMATION

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.
