The Analog Devices MAX8647ETE+T is a DC-DC regulator configured as a switched-capacitor charge pump LED driver. The 1 MHz switching frequency keeps external capacitors small, and the 2.7 V to 5.5 V input range covers single-cell Li-ion and Li-poly battery rails.
Six regulated outputs at 24 mA each is enough for a small-to-medium LCD backlight array or a multi-LED flash module. The 5 V output is fixed — no external resistor setting — which simplifies the layout but means the driver is matched to a 5 V LED string. I²C dimming gives you digital brightness control without an extra PWM pin; the host writes a register over the two-wire bus.
ROHS3 compliant, so no conflict with EU or California RoHS requirements. No NRND or EOL notices are recorded for this order code — it remains a current-production part available through the independent distribution channel.
