Placement of regulators for core voltage levels closer to the chips that need them Usage of unique materials like ECMs in PCBs and packages to provide power rail capacitance Package-level and ...
Some time ago, while designing the PCB for the Sony Vaio replacement motherboard, I went on a quest to find a perfect 5 V boost regulator. Requirements are simple – output 5 V at about 2A , with input ...

Linear Technology Corporation launched the LTM4636, a 40A step-down µModule® switching regulator with 3D construction for quicker heat dissipation and cooler operation in a small package. By stacking ...
This article addresses some of the fundamentals of laying out a switching-regulator board. Although it focuses on a step-up switching-regulator, the concepts it covers are also useful when working ...
So-called “conventional wisdom” sometimes takes a long time to change and recognize new realities. Among the many common beliefs is that switching regulators are relatively “high noise” devices, while ...
The LTM4644 integrates four separate constant frequency controlled on-time valley current-mode regulators, power MOSFETs, inductors, and other supporting discrete components (Fig. 1). Each of the four ...
