Overview

The LTC3562 is a quad high eff iciency monolithic synchronous step-down regulator with an I2C interface. Two regulators are externally adjustable and can have their feedback voltages programmed between 425mV and 800mV in 25mV steps (Type A). The other two regulators are f ixed output regulators whose output voltages can be programmed between 600mV and 3.775V in 25mV steps (Type B). All four regulators operate independently and can be put into pulse skip, LDO, Burst Mode operation, or forced Burst Mode operation through I2C control. The Type-A regulators have separate RUN pins that can be enabled if I2C control is unavailable. The 2.85V to 5.5V input voltage range makes the LTC3562 ideally suited for single Li-Ion battery-powered applications. At low output load conditions, the regulators can be switched into LDO, Burst Mode operation, or forced Burst Mode operation, extending battery life in portable systems. The quiescent current drops to under 100μA with all regulators in LDO mode, and under 0.1μA when all regulators are shut down. Switching frequency is internally set to 2.25MHz, allowing the use of small surface mount inductors and capacitors. All regulators are internally compensated. The LTC3562 is available in a low prof lie 3mm × 3mm QFN package.
