DESCRIPTION

The LTP?8800-1A is a 150A 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 LTP8800-1A 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 LTP8800-1A preserves high efficiency at high conversion

ratios by utilizing a resonant switching architecture

that eliminates high voltage switching losses.

The LTP8800-1A is available in a 22mm × 24mm × 6.7mm

surface-mounted open frame package.
