Description
The BW7385A is a highly-integrated, low startup
current, TM (Transition Mode), fixed on- time PFC
control and 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, over voltage protection, over load
protection. The COMP pin controls the duty by
connected an RC compensation network to ground
and forming the closed loop feedback control.
The BW7385A improves the performance and
reduces the cost of the LED driver. It is a 6-pin
SOT-26 package.
