BW7386
Accuracy Constant Current LED Driver
FEATURES
Accuracy Constant Current Low BOM Cost Current Mode/Fixed Frequency Control Gate Output Voltage Clamp LED Open Protection(OVP) Over Current Protection (OCP) 300mA Driving Capability for OUT Pin
DESCRIPTION
The BW7386 current, is a highly-integrated, low startup mode, and fixed switching current
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.
