Description
The GL8211/11B is a highly-integrated, low
startup current, average current mode, one cycle
control PFC and fixed switching frequency PWM
controller. These functions enable the LED driver
to easily meet the accuracy average LED current
and high power factor requirements. The
integrated functions also include the LED short
protection, open protection, and internal over
temperature protection. The COMP pin controls
the duty by connected an RC compensation
network to ground and forming the closed loop
feedback control. To protect the external power
MOSFET from being damaged by supply over
voltage, the GL8211/11B OUT pin voltage is
clamped to about 15V.
The GL8211/11B improves the performance and
reduces the cost of the LED driver. It is a 6-pin
SOT-26 package.
