LTM4681: Quad 31.25 A or Single 125 A µModule Regulator with Digital Power System Management

The LTM4681 is a quad 31.25 A or single 125 A step-down μModule^® (power module) DC-to-DC regulator featuring remote configurability and telemetry-monitoring of power management parameters over PMBus.

The LTM4681 is composed of digitally programmable analog control loops, precision mixed-signal circuitry, EEPROM, power MOSFETs, inductors, and supporting components.

Key Features and Benefits

●  Configurable quad outputs provide flexibility for use as quad, triple, dual, or single output
●  Parallel and current share multiple modules for higher current, reach up to 1000 A with the minimum solution size in the market
●  Digital power supply management allows user to command and supervise a system’s power condition and consumption via a digital bus, reducing time to market and downtime

Applications

●  General purpose: FPGA, core power, ATE
●  Industrial automation
●  Aerospace and defense
●  Communications
●  Healthcare
●  Instrumentation and measurement
●  Building and infrastructure
