The LTP®8802A-1B 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.
The LTP8802A-1B 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 LTP8802A-1B preserves high efficiency at high conversion ratios by utilizing a quasi-resonant architecture that reduces high voltage switching losses. The LTP8802A-1B is available in a 22mm × 24mm × 22mm surface-mounted open frame package.
APPLICATIONS
- High Current Distributed Power Systems
- Servers, Network, and Storage Equipment
- Intelligent Energy Efficient Power Regulation
