BD6071HFN is a white LED driver IC designed for driving up to three LEDs in series with a boost DC/DC converter. It can boost output voltage up to 14V while maintaining constant current, ensuring stable LED operation without current variation. The device features synchronous rectification, eliminating the need for an external Schottky diode, which contributes to a compact design. Brightness can be adjusted using an external PWM signal, and the driver includes a soft start function to prevent inrush current. It operates within a power supply voltage range of 2.7V to 5.5V and has a typical switching frequency of 1MHz. The quiescent current is low at 0.1OºA, making it suitable for battery-powered applications. The operating temperature range is from -30¬8C to +85¬8C, and the device is housed in a small HSON8 package measuring 2.90mm x 3.00mm x 0.60mm. This LED driver is applicable in various devices, including mobile phones, portable game machines, and backlighting for displays, making it a versatile choice for engineers looking to implement LED solutions in compact electronic designs.
Switching Regulator type LED Driver Series for small LCD backlight are boost DC/DC converters possible to drive the white LEDs at constant. It is possible that turning on white LED steadily by a series connection which has no current variation, and by a fast transient response with current mode. With synchronous rectification (no external schottky diode required) and small package, they can save mount space. BD6071HFN suited over voltage and over current limit from BD6072HFN.
