集成I2C,应用于功率敏感的手持设备处理器的四路DC-DC稳压器

资料介绍
The LTC3562 quad output step-down regulator is designed for multicore handheld microprocessor applications that operate from a single Li-Ion battery. Its four monolithic, high efficiency buck regulators support Intel’s mobile CPU P-State and C-State energy saving operating modes. The output voltages are independently controllable via I2C, and each output can be independently started and shut down. Designers can choose from power saving pulse-skipping mode or Burst Mode operation, or select low noise LDO mode. The space-saving LTC3562 is available in a 3mm ×3mm QFN package and requires few external components.
