The LTP™8800-2 is a 135A 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. The LTP8800-2 comprises 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 LTP8800-2 preserves high efficiency at high conversion ratios by utilizing a quasi-resonant architecture that reduces high voltage switching losses. The LTP8800-2 is available in a 22mm × 24mm × 6.7mm surface-mounted open frame package.
