Silicon Monolithic Integrated Circuit
LED Driver for cellular phone
BD82103GWL
・ 2light or 3light parallel LED driver is mounted
・ 16-step LED current adjust function
・ Inter-LED relative current accuracy: 5% or less
・ Driving control via a single-line digital control interface
・ Automatic transition charge pump type DC/DC converter (×1,×1.5, ×2)
・ High efficiency achieved (90% or more at maximum)
・ It transits for the most suitable power operating by the LED terminal process
of the 3rd light when 2 light driving
・ Various protection functions such as output voltage protection and thermal shutdown circuit are
mounted.
