In summary, the LTC3675 PMIC features eight channels: four high current, high efficiency synchronous step-down regulators; a high current/high efficiency buck-boost regulator; a high current synchronous boost regulator; a 40V dual string LED driver; and one always-ON LDO linear regulator. Also included is power sequencing, dynamic voltage scaling control, a pushbutton interface controller for power-on, off, reset control, and sequencing for predictable power-up. Available in a compact QFN package, the LTC3675 is a complete power management solution for general-purpose high-power applications in the portable, industrial, and medical market segments.
