AX9300
High Power Factor and Accuracy
Constant Current LED Driver
GENERAL DESCRIPTION
The AX9300 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 AX9300 OUT pin voltage is clamped to about 15V.
The AX9300 improves the performance and reduces the cost of the LED driver. It is
a 6-pin SOT-26 package.
