30A, Scalable to 180A, µModule Regulator in 9mm x 15mm BGA PackageMILPITAS, CA - November 16, 2016 - Linear Technology introduces the LTM4647, a 30A step-down µModule (power module) regulator. The LTM4647 includes the inductor, MOSFET, DC/DC controller and supporting components in a 9mm x 15mm x 5.01mm BGA package. The device's conversion efficiency from 12VIN to 1VOUT at 30A is 87%, when delivering a full 30A
continuously without a heat sink or air flow at 70℃ ambient. The LTM4647 can deliver up to
180A by current sharing six devices in parallel.
Total output voltage DC accuracy is guaranteed at ±1.2% over reference, feedback
resistor, line, load and temperature (-40℃ to 125℃), and the onboard remote sense amplifier compensates for the voltage drop caused by trace impedance of the PC board due to large load
currents. With its small package size and precise voltage accuracy, the LTM4647 meets the PCB area constraints of densely populated system boards to power low voltage and high current devices such as FPGAs, ASICs, microprocessors and GPUs. Applications include PCIe boards, communication infrastructure, cloud computing-based systems, test and measurement, medical and industrial equipment.
Input voltage range is 4.7V to 15V, and output voltage can be set by an external single resistor ranging from 0.6V to 1.8V. Output voltage tracking and soft-start features allow users to set sequencing with other system rails. The switching frequency can be set by an external single resistor ranging from 400kHz to 700kHz or can be synchronized to an external clock. Fault protection features include overvoltage protection, overcurrent protection, and temperature monitoring.
The LTM4647 operates from -40℃ to 125℃. 1,000-piece pricing starts from $29.70
each. For more information, visit www.linear.com/product/LTM4647.
