Step-down μModule regulator produces 15A output from inputs down to 1.5V—no bias supply required

1.5V to 5.5V input, 0.8V to 5V output from a 15mm × 15mm × 4.32mm LGA package

Alan Chern and Jason Sekanina

Abstract

The LTM4611 switch mode, step-down DC/DC Module (micromodule) regulator is described. It easily fits into point-of-load (POL) applications needing high output current from low voltage inputs, and efficiency and thermal performance remain high across the entire input voltage range.
