What this part is and where it fits
The Analog Devices MAX8647ETE+T is a DC-DC regulator configured as a switched-capacitor charge pump LED driver. It drives six outputs at 24 mA each, controlled via I²C dimming, making it a direct fit for backlight and camera flash applications in portable devices. 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.
Key ratings and what they mean for the BOM
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. The -40°C to 85°C operating range covers industrial and outdoor telecom use, not just consumer handhelds.
Lifecycle and compliance
The MAX8647ETE+T carries an active lifecycle status from the manufacturer. 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.
