Overview
BD6067GU LED Drivers for LCD Backlights White Backlight LED Drivers for Small to Medium LCD Panels (Switching Regulator Type) BD6067GU, BD6069GUT, BD6071HFN, BD6072HFN No.
11040ECT19 ●Description 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 with synchronous rectification.
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 BD6069GUT/BD6072HFN.
●Features 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 game machines, Inter-phone camera, audio player, portable DVD player, back light for printer display etc… and support light of the camera for the mobile phone, simple flash.
And, these can use power supply for OEL.
