Introduction
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 ...
