Linear Technology’s LTM4644 quad output step-down µModule (micromodule) regulator is configurable as a single (16A), dual (12A, 4A or 8A, 8A), triple (8A, 4A, 4A) or quad (4A each) output regulator. It includes dc/dc controllers, power switches, inductors, and compensation components in a 9 mm x 15 mm x 5.01 mm BGA package. Just eight external ceramic capacitors (1206 or smaller case sizes) and four feedback resistors (0603 case size) are required to regulate four independently-adjustable outputs between 0.6V to 5.5V. Separate input pins enable the four channels to be powered from different or a common supply rail(s) from 4V to 14V. The LTM4644 is ideal for applications in communications, data storage, industrial, transportation and medical systems. Pricing starts at $22.85 each/1,000.
