LTP8802A-1BIPV#PBF

LTP8802A-1BIPV#PBF is a 140A step-down μModule® (micromodule) regulator that provides microprocessor core voltage from a 54V power distribution architecture. It features remote configurability and telemetry monitoring of power management parameters over PMBus, an open standard I²C-based digital interface protocol. It is comprised of a programmable digital control system with precision mixed-signal circuitry, EEPROM, power MOSFETs, planar transformer, inductors, and supporting components. Its high level of integration minimizes component count and design time and maximizes flexibility and power density. It preserves high efficiency at high conversion ratios by utilizing a quasi-resonant architecture that reduces high voltage switching losses. Applications include high current distributed power systems, servers, network, and storage equipment, intelligent energy efficient power regulation.
