A Design of 16-Channel LED Driver IC for full color LED Display
초록
영어
A 16 channel LED driver IC has been developed for Full color LED display system. the 16 channel driver IC consists of constant current regulator function and channel control function. The basic building circuit of the constant current regulator are differential pair, current mirror, negative feedback loop. It use for drawing current independent of temperature and supply voltage. LED brightness is correctly controlled by Dot correction and PWM(Pulse Width Modulation). A real-time monitoring of IC temperature (120°C/160°C) and LED status (open/short) is provided by LED driver IC and the user can receive warning and get information on problems. A 16 channel LED driver IC for full color LED display is produced using 0.35um BCD process and the size is 2.5mm x 2.5mm.
