Silicon 'sawdust’ in a graphene cage boosts battery performance

Silicon 'sawdust’ in a graphene cage boosts battery performance
Scientists have been trying for years to make a practical lithium-ion battery anode out of silicon, which could store 10 times more energy per charge than today’s commercial anodes and make high-performance batteries a lot smaller and lighter. But two major problems have stood in the way: Silicon particles swell, crack and shatter during battery charging, and they react with the battery electrolyte to form a coating that saps their performance.

Buck converter delivers high efficiency over full load range

Buck converter delivers high efficiency over full load range
Designed for battery-powered applications such as mobiles and wearables, the AP3405 DC/DC buck converter has been introduced by Diodes Incorporated. Delivering high efficiency under light and heavy loads, the converter's fixed switching frequency of 2MHz reduces the size of external components while a small U-DFN2020-8 package saves board area.

Common mode difference amplifier offers 97dB min CMRR

Common mode difference amplifier offers 97dB min CMRR
Linear introduces the LT6375, a unity-gain difference amplifier with integrated precision matched resistors, which precisely level shifts and buffers small difference signals while rejecting up to ±270V common mode. The A-grade version achieves unprecedented performance: CMRR is 97dB (min), initial gain error is 35ppm (max), gain drift is 1ppm/°C (max) and gain nonlinearity is 2ppm (max) with a common mode divide ratio of 25:1.
