White LED Driver


Model A8435 charge pump white LED driver uses a proprietary control scheme to output well-matched LED currents for up to four channels while maximizing efficiency over most of the life of the Li-Ion battery. It accepts an input range of 2.7 to 5.5 v and delivers up to 30 ma for each of the four regulated current sources. Current can be set by four methods: selecting RSET value, 2-bit parallel control with three levels, PWM control, or serial programming.
