Microchip Technology has introduced the TC1303/TC1304 and TC1313 Series of power management ICs that combine a synchronous buck switching ... LDO regulator can operate at loads of up to 300 ...

A Buck, Boost, or Buck-Boost switching ... A search for switching regulators or controllers throws up thousands of parts, and it’s possible to select one specifically well suited for any desired ...

At 90% efficiency, they’re generally much more efficient and smaller than linear regulators. Their disadvantages are noise and complexity. A buck converter steps voltage down, producing voltage ...

Intersil has announced ISL91127 and ISL91128, two buck boost regulators with 4.5A built-in switches and up to 96% efficiency. Aimed at battery-operated devices, they work from 1.8 to 5.5V and offer ...

It’s still possible to make switching regulators from first principles though, which is what [Aaron Lager] has done by designing a buck regulator from a quad op-amp IC, It’s an entry in our Op ...

enabling designers to eliminate a second-stage low dropout regulator (LDO), saving BOM cost and board space. The buck regulators connect to the AC line to power Renesas MCUs, sensors and other digital ...
