Linear Technology's LTM4611 is a complete switch mode DC/DC µModule point-of-load regulator capable of generating its own 5V N-channel MOSFET gate drive for very efficient voltage conversion from 3.3VIN or less to loads as low as 0.8V at up to 15A.
Alternative traditional low input voltage high power switch mode DC/DC converters with N-channel MOSFETs require a second regulator circuit to provide the 5V gate drive needed for logic level MOSFETs. Conversion efficiency for the LTM4611 at full load (15A) is 92% for 3.3VIN to 2.5VOUT.
Applications include systems with only 3.3V, 2.8V or 2.5V as the main power rail such as compact data storage and RAID systems, ATCA and optical networking cards, as well as medical and industrial equipment.
