The LTC®3562 quad output step-down regulator is designedfor multicore handheld microprocessor applications thatoperate from a single Li-Ion battery. Its four monolithic, higheffi ciency buck regulators support Intel’s mobile CPU P-Stateand C-State energy saving operating modes. The outputvoltages are independently controllable via I2c, and eachoutput can be independently started and shut down. Designerscan choose from power saving pulse-skipping mode orBurst Mode® operation, or select low noise LDO mode. Thespace-saving LTC3562 is available in a 3mm × 3mm QFNpackage and requires few external components.
Linear 公司的LTC4310是絕緣的雙向I2c總線通信器件，每個器件可把I2c邏輯狀態編碼成信號，通過絕緣層傳輸到另一個器件．接收器件解碼，并驅動I2c總線到適當的確邏輯狀態．主要用在絕緣的I2c, SMBus和PMBus 接口，絕緣電源，以太網供電和正到負電源通信．本文介紹了LTC4310主要特性，典型應用以及多種應用電路框圖．
