FEBFL77904-L82L08A-GEVB

FEBFL77904-L82L08A-GEVB is a high-performance LED driver designed to provide reliable, efficient operation and superior performance in demanding lighting applications. It features a total current of 8A and a wide input voltage range from 3V up to 24V. The driver is optimized for applications including street lamps,backlight and general commercial lighting applications.

FEBFL77904-L82L08A-GEVB evaluation board provides flexibility and convenience for quick development of LED lighting applications. It contains two boards: the FEBFL77904-L82L08A-GEVB main board and a control board. The main board is composed of a copper baseplate and four copper heat spreaders distributed around the baseplate. A pair of extruded aluminum channels make up the heat sink of the driver and the control board is attached to the fan on one side. It features an LED connection to the main board, so that the LED lighting application can easily be determined and evaluated.

The board is designed to provide efficient and reliable performance in demanding LED applications. It features a total current of 8A and a wide input voltage range from 3V up to 24V. It supports a wide range of lighting applications such as street lamps, backlight, and general commercial lighting. It is equipped with comprehensive diagnostics, overload protection, and short circuit protection. The board also provides overload protection when running at high temperatures.

The FEBFL77904-L82L08A-GEVB board employs three main functions to properly drive and control any LED device. The first function is the DC/DC converter, which is used to convert the input voltage from 3V to 24V to the required output voltage for the LED device. The second function is the power FET driver, which is used to directly drive the power FETs. The last and most important function is the voltage feedback loop, which is used for closed loop operation for accurate current and voltage regulation.

The FEBFL77904-L82L08A-GEVB operation is based on the LED current sensing via the LED Vcc pin. The LED current is measured with a shunt resistor to the ground, and the feedback is compared with the output voltage. The Error Amplifier and OVP Comparator adjust the output voltage and current, which drives the Gate Driver to pulse width modulate the signal. This ensures that the LED current is accurately maintained within the range of +/-5%.

The FEBFL77904-L82L08A-GEVB offers superior performance and reliability in LED lighting applications. It has a wide range of input voltage and output current, which makes it ideal for different types of LED lighting applications. Its advanced current and voltage control allows for efficient and accurate operation of LED devices. Its comprehensive diagnostics and protection make it a safe and reliable LED driver for various applications.
