BD9206EFV-E2 is a PMIC (Power Management IC) LED Driver that is capable of powering white, blue and green LEDs from a 3V to 6V power source. It is suitable for a wide range of applications, such as for field signs, decorative lightings, backlit signs, decorative logo lightings, interior and exterior automotive lighting, and mobile phones. This PMIC LED driver features the following features:

• High-Efficiency LED Driver: BD9206EFV-E2 implements high-efficiency LED driver technology that enables designers to lower component cost and reduce power consumption.
• Low-Noise Output: This PMIC LED driver is designed to provide a low-noise output, and has a high-accuracy current control which ensures stable, consistent output.
• Easy-to-Use Functions: This PMIC LED Driver includes a variety of easy-to-use functions, such as dimming control, thermal protection, and over-current protection.
• Compact Form Factor: This PMIC LED Driver is highly compact, and can be used in space-limited applications.

The BD9206EFV-E2 is capable of providing current control for single to multiple strings of LEDs, with a high-efficiency from 3V to 6V, and high-accuracy current control that ensures stable, consistent output. It is designed to provide maximum current accuracy over all input and output currents, along with a wide temperature range of -40℃ to +105℃.

The BD9206EFV-E2 works on the principle of buck converter (dc-dc converter). It uses a switch to convert the higher voltage to a lower voltage by cutting off or conducting the current. As its input voltage is greater than output voltage, the switch is turned on and off. This is done at certain intervals and the duration of each on and off period is determined by a control signal. This control signal is generated by the current feedback control circuit, which compares the programmed current with the panel LED current and adjusts the switch pulse width accordingly.

The main application fields of the BD9206EFV-E2 include decorative lightings, backlit signs, decorative logo lightings, interior and exterior automotive lighting, and mobile phones. It is also suitable for field signs, as it can support a wide range of currents from 10 mA to 1000 mA. With its wide operating temperature range and high-efficiency power conversion, this PMIC LED Driver is a reliable, cost effective solution for a variety of applications.
