Vicor DCM5614 Isolated Regulated DC Converter comes in a VIA™ package, offers up to 96% efficiency, and operates from 180VDC to 400VDC. This DCM Converter features flexible mechanical mounting options with low top- and bottom-side thermal resistances due to the thermal management...

Surface Mount, Non-isolated DC-DC Converter Offers Extreme Efficiency at a Low Cost CUI Inc today announced the addition of its first four contact, surface mount, non-isolated converter to its dc-dc converter line. The ultra-thin VXO78-500-M features a 500mA output current, no-load...

Nichicon Corporation’s SLB series of small lithium-ion rechargeable batteries, featuring ultrafast charge/discharge rates, long life, and high stability, have been adopted for use on the stylus pens (“S Pens”) of the Galaxy Note 10 and Note 10+, smartphone models by Samsung...

The CT04120 from Murata is a small form factor lithium-ion battery that can support 10C Charging rates without the need for a battery controller IC. Continuous discharge at a 10C rate is also supported by these rechargeable batteries. In addition, since the internal resistance is low...

Tech note from Richtek on buck converter profiling. Link here The synchronous buck circuit is wildly used to provide non-isolated power for low voltage and high current supply to system chip. To realize the power loss of synchronous buck converter and to improve efficiency is important...

peter6960 shared a new project. It' s about a 18650 cells power brick with onboard battery management system. He writes: While I cannot afford a Tesla PowerWall, I’ve spent some time drawing up a PCB to house 7x 18650 cells in series. Each board has onboard Battery Management:...
