BD9420F-GE2 is a member of the Market Leader Power Management Integrated Circuit (PMIC) LED Drivers family that brings a broad variety of features for LED drive applications. This LED Driver has both constant current and pulse width modulation (PWM) outputs that enable it to simultaneously drive both standard and high-power LED loads with the same output channel. BD9420F-GE2 is an ideal solution for applications such as high-power LED lighting, solar power systems and LCD TVs.

The BD9420F-GE2 is capable of handling up to 1W of output power at a 48 V supply voltage and includes a range of protection features such as under-voltage protection, over-voltage protection and over-temperature protection. The LED Driver also provides flexibility in voltage, current and LED array recognition, allowing for higher power and longer life. Additionally, the device offers an adjustable switching frequency and can be set between 1kHz and 240 kHz.

The BD9420F-GE2 features a number of features that make it the ideal solution for LED drive applications. Its constant current output mode is capable of extremely precise current regulation, thanks to the built-in 0.08% capacitive accuracy voltage reference. The current regulation is further enhanced by a built-in thermal compensation. The adjustable switching frequency provides the ability to customize the PWM output frequency, allowing for noise control and optimization of system efficiency.

The BD9420F-GE2 also offers configurable protection and fault detection functions, which offer users the ability to monitor their systems and set thresholds to maintain safe operation of their systems. Additionally, the LED Driver includes two built-in current sensing DACs that provide a high resolution of the LED current, allowing for unparalleled accuracy and reliability when driving an LED load. Furthermore, the device supports current balancing, which keeps the LED load evenly balanced both during and after the current regulation.The BD9420F-GE2 LED Driver is designed to provide low power losses, due to the low switching losses and low RDS(ON) internal MOSFETs. This enables the device to remain cool, even under high power output conditions, and also reduces energy consumption. Furthermore, the device incorporates over-voltage protection, under-voltage protection and over-temperature protection to ensure that the device remains safe to use in any environment.

In conclusion, the BD9420F-GE2 Power Management Integrated Circuit (PMIC) LED Driver is the ideal solution for demanding LED drive applications. It provides constant current and pulse width modulation (PWM) outputs simultaneously, and its adjustable switching frequency allows for total noise control and system efficiency optimization. It also features protection and fault detection functions, as well as current balancing and a 0.08% accurate voltage reference. These features make it a necessary component for all modern LED lighting systems.
