LTP8803-1A

160A DC/DC Power µModule Regulator

with PMBus Interface

FEATURES

DESCRIPTION

The LTP™8803-1A is a 160A step-down μModule^®regula

High Efficiency at High Frequency

Up to 91.8% Efficiency at 600kHz, 54V to 1.2V

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.

OUT

PMBus-Compliant I C Serial Interface

Monitor Voltage, Current, Temperature, and Faults

Internal EEPROM Fault Log Record

Digitally Programmable Control Loop

Program Voltage, Current Limits, Soft-Start/Soft-

Stop, Frequency, Synchronization and Phasing,

Power-Good, Warnings and Faults

The LTP8803-1A is comprised of a programmable digi-

tal 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 maxi-

mizes flexibility and power density.

Wide Input Voltage Range: 45V to 65V

Output Voltage Range: 0.5V to 1.5V

Optimized for 45V to 65V to 1.2V

OUT

0.5% Maximum DC Output Error with Differential

Remote Voltage Sense

3% Current Readback Accuracy

Parallel and Current Share Multiple μModule ICs

Pin Compatible with LTP8800-1A and LTP8800-4A

(Optimized for 0.8V

22mm × 24mm × 22mm Surface-Mounted Package

The LTP8803-1A preserves high efficiency at high conver-

sion 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.
