The LTP8803-1A is a 160A step-down μModule®regulator that provides microprocessor core voltage from 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.The LTP8803-1A 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.The LTP8803-1A preserves high efficiency at high conversion ratios by utilizing a resonant switching architecture that eliminates high voltage switching losses.The LTP8803-1A is available in a 22mm × 24mm × 22mm surface-mounted open frame package.ApplicationsHigh Current Distributed Power SystemsServers, Network, and Storage EquipmentIntelligent Energy Efficient Power Regulation
