Supercapacitor backup power management module for 2.9 to 5.5-V supply rails
Analog Devices announces the Power by Linear LTC4041, a complete supercapacitor backup power management system for 2.9V to 5.5V supply rails that must be kept active during a main power failure. Supercapacitors have higher power density than batteries, making them ideal for systems requiring high peak power backup for short periods of time. View the LTC4041 product […]
New 1.2-kV IGBTs provide better efficiency
Infineon Technologies AG is launching a new 1200 V IGBT generation TRENCHSTOP IGBT6. It is the first discrete IGBT duopack on the market manufactured on 12-inch wafer size. The new IGBT technology is designed to fulfill the increasing customer requirements for high efficiency and high power density. The product family was optimized for use in […]
Here’s what happens when lithium-ion batteries are drastically overcharged
Lithium batteries have a high energy density so they can store a lot of energy in a small volume. But they can go up in smoke when bad things happen. Recently we recorded a short video to show what can happen during one of those bad things – overcharging. Excessive charging can bring on thermal […]
Dual-input boost-buck charging ICs support USB Power Delivery spec
A growing number of portable devices, including notebook PCs, are adopting the USB Type-C PD standard that can charge up to 100W, providing a common charging platform. At the same time wireless charging is gaining traction, increasing the demand to support both charging methods. However, in order to deliver a wide power supply range required […]
