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. And, BD6069GUT/BD6071HFN/BD6072HFN are white LED driver ICs wit.
1) Boost DC/DC converter 2) Adjustment of brightness by external PWM pulse 3) Possible to driving 3 LEDs (BD6071HFN ) 4) Possible to driving 4 LEDs (BD6069GUT, BD6072HFN) 5) Possible to driving 8 LEDs (BD6067GU) 6) Soft start function (BD6067GU, BD6069GUT, BD6071HFN, BD6072HFN) 7) Synchronous rectification Boost DC/DC converter (BD6069GUT, BD6071HFN, BD6072HFN) 8) No external schottky diode required (BD6069GUT, BD6071HFN, BD6072HFN) 9) Output Open
• Short protect (BD6069GUT, BD6071HFN, BD6072HFN)
●Applications
These drivers are applicable for various fields such as mobile phones, portable gam.
