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.
APPLICATIONS
LED lighting
Down light
Tube lamp
PAR lamp
Bulb
