DESCRIPTION

The LTP?8803-1A is a 160A 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 LTP8803-1A 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 LTP8803-1A preserves high efficiency at high conversion

ratios by utilizing a resonant switching architecture

that eliminates high voltage switching losses.

The LTP8803-1A is available in a 22mm × 24mm × 22mm

surface-mounted open frame package.
