ORDER INFORMATION

DESCRIPTION

The

BW7385 is a THD and Efficiency

adjustable, high accuracy and high power factor

constant current PWM controller. This is capable of

controlling THD and Efficiency optimization by an

external resistor. These functions enable the LED

driver

to

easily

meet

rule

of

LED

current

requirements

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.

BW7385 also provides gate driving voltage

clamping, VCC over voltage protection and system

output open/short circuit protection to increase IC

performance.
