DESCRIPTION
The BW7386 is a highly-integrated, low startup
current, current mode, and fixed switching
frequency PWM controller. These functions enable
the LED driver to easily meet the accuracy average
LED current requirements. The integrated functions
also include the LED 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 BW7386 OU T pin voltage is
clamped to about 17V. The BW7386 improves the
performance and reduces the cost of the LED driver.
It is a 6-pin SOT-26 package.
