LTP8800-1A

150A DC/DC µModule Regulator

with PMBus Interface

FEATURES

DESCRIPTION

The LTP™8800-1A is a 150A step-down μModule regula-

High Efficiency at High Frequency

Up to 87.0% Efficiency at 1MHz, 54V to 0.8V

tor that provides microprocessor core voltage from 54V

power distribution architecture. It features remote config-

urability 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 conver-

sion ratios by utilizing a resonant switching architecture

that eliminates high voltage switching losses.
