3 Description
The LMM104RM0 module is an evolution within the TI
intermediate bus converters family. This module is a
high-efficiency, regulated, non-isolated, 1.6kW thermal
design power (TDP), in a standard quarter-brick
footprint. The modular design provides a high-power
density power conversion from 48V bus to a regulated
12V output, with options for parallel connection with
multiple modules and current sharing through activecurrent
control.
