Single Phase Step-Down DC/DC Controller With Digital Power System Management & Input Current Sense

The digital power supply market has achieved rapid progress in the recent years. Easy configuration, accurate telemetry, convenient fault analysis, and reliability are the trends for the modern digital power supply, which are all provided by Linear’s new digital power controller, the LTC®3883. The LTC3883 is a single phase synchronous buck controller with integrated N-channel MOSFET drivers. The input voltage range is from 4.5V to 24V; the output voltage can be remotely sensed, from 0.5V to 5.5V. The PMBus provides programmable voltage, current limits, sequencing, margining, OV/UV thresholds, and frequency synchronization. Over the operation temperature range, the output voltage accuracy is guaranteed to be within ±0.5%. The LTC3883’s control loop is analog peak current mode control, which provides excellent the stability as well as a fast transient performance. The LTC3883 uses a sense resistor to accurately sense the power stage and the chip’s input current. Also, LTC3883 contains Linear Technology’s new, patent pending, inductor DCR auto calibration function. With this new method, the output current read back accuracy can be within 3% regardless of inductor tolerance. The LTC3883 is supported by LTpowerPlay software, an easy-to-use and powerful graphical user interface program. The LTC3883 can be used for computing, telecom equipment and storage systems.
