15 Amp Switch mode DC/DC uModule from linear works at low Vin of 1.5 V
Linear has launched the LTM4611, a complete switch mode DC/DC uModule point-of-load regulator. It is capable of generating its own 5V N-channel MOSFET gate drive for voltage conversion from 3.3VIN or less to loads as low as 0.8V at up to 15A.
The LTM4611 offer conversion efficiencies of 92% at full load (15A) for 3.3VIN to 2.5VOUT, 88% for 2.5VIN to 1.5VOUT, and 81% for 1.5VIN to 0.9VOUT. It is suitable for 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. This module consists of the main DC/DC power circuit and the gate drive circuit and inductors, MOSFETs, input and output bypass capacitors and weighs only 2.6g. The device boasts ±2% total DC output error over temperature, including line and load regulation. To increase output capability to 30A, 45A or 60A, two, three or four LTM4611 DC/DC uModule devices can be paralleled to share current.
