Figure 1. LTM4657, LTM4626, and LTM4638 offer different output current ratings using the same pinout. The LTM4657 and LTM4626 use lower profile inductors to reduce the overall height

20 VIN, 8 A, High Efficiency, Tiny Package Step-Down µModule Device

Timothy Kozono, Applications Engineer, Analog Devices

The LTM4657 is part of the family of tiny, high efficiency, identical pin-out, step-down µModule® devices. The LTM4657 is designed to operate at lower switching frequencies than the LTM4626 and LTM4638 as it provides higher efficiency within its 8A output current range. The LTM4657 bridges the gap between th

Non-Isolated Current Sensing Solutions

ROHM Semiconductor Technical Team

Many electronic devices are required to measure current, either to support one of their features or as a means of regulation for safety and control. In the former case, energy measurement tools and power management systems are common examples, while in the latter case, inverter feedback loops and over cu
