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.Compact I2C-Controllable Quad Synchronous Step-Down DC/DC Regulator for Power-Conscious Portable Processors Design Note 442 Jim Drew Introduction The “Type B” regulators (R600B and R400B) do not require The LTC3562 quad output step-down regulator is designed external programming resistors because the resistors are for multicore handheld microprocessor applications that integrated on-chip. The values of the internal feedback operate from a single Li-Ion battery. Its four monolithic, high resistors are adjusted through the I2C port, resulting in efciency buck regulators support Intel’s mobile CP……
