This is a reference design report for a dual output 17.5 W power supply employing InnoSwitch™-EP INN2904K. It operates in an input voltage ranging from 85 VAC to 484 VAC and delivers an output of 12 V ...

Some systems, such as optical networks, require more than one negative voltage. A common procedure is to boost the main negative supply of –5V to –10V and then reduce it with a linear regulator to –9V ...

Apple's pair of dual-output USB-C are shipping, and are well-suited for many of your daily devices. Surprisingly, Apple had a few hardware announcements up its sleeve at WWDC this year. Most attention ...

When low cost in small volumes using readily available parts is a primary concern, standard approaches to isolated dc-dc conversion may not be suitable. The author's circuit, although admittedly ...
