Although the LED light has become the most common light source used in many activities, it is one of the most difficult light sources to control. In order to make LED lighting function properly and effectively, LED driver ICs along with microcontroller systems are essential. As one of the popular LED drivers, the BD9413F-GE2 (BD9413F-GE2) is widely used in various applications, especially the solid-state lighting systems.The BD9413F-GE2 is a linear low-noise step-up DC/DC converter with inductor in the current-mode control circuit. It is specially designed for driving high-power LEDs, mainly used in the application of multi-meters backlight and other indicators. Based on the same structure, the BD9413F-GE2 benefits for its low noise, fast response and high efficiency.The BD9413F-GE2 adopts the pulse frequency modulation (PFM) to control the entire MOSFET switch. It provides a high-side current-sense circuit and a low-side current sense circuit to sense the current in the high-side device and the low-side device. It is featured as a fast over-current protection, a brief LED open-circuit protection and a thermal protection. When the LED is illuminated for a long time, the BD9413F-GE2 can intelligently adjust the switching frequency and it is selected to avoid the audible noise.Due to its embedded short-circuit protection circuit, the BD9413F-GE2 supports a wide range of ambient temperatures with its correct current-mode control. Moreover, it has a wide adjustable output voltage with a few external components. The maximum output current is 25mA, and the BD9413F-GE2 also enables an dimmer function to adjust the maximum output current. The BD9413F-GE2 is suitable for applications, such as automotive lighting systems, backlight metering and other purposes. Its low voltage operation, low noise, high efficiency and wide range of temperature support make it applicable in the harsh temperature environment. Therefore, this LED driver IC will be a better choice to build a modern and energy-efficient lighting system.
