The LTP8800-1AIPV device is a 150A DC/DC μModule regulator with PMBus interface

Overview:

The LTP8800-1A is a 150A step-down μModule regulator that delivers microprocessor core voltage over a 54V distribution architecture. It enables remote configuration and telemetry monitoring of power management parameters via PMBus (an open standard digital interface protocol based on I2C). The LTP8800-1A includes a programmable CNC system with precision mixed-signal circuits, EEPROM, power MOSFETs, planar transformers, inductors, and supporting components. Its high level of integration allows for sufficient reduction in the number of components and design time, while increasing flexibility and power density. The LTP8800-1A utilizes a resonant switching architecture to eliminate high voltage switching losses, thereby maintaining high efficiency at high conversion rates.
