IR's Full-featured, Flexible Approach to Implementing Complete AMD(R) CPU Power Solution
The IR3514 control IC enables designers to migrate from AMD processors requiring a parallel VID to SVID processors without the need to change the motherboard. Combined with the IR3507 phase IC, the IR3514 provides Power Saving Interface (PSI) capability to turn phases(N-1) on or off depending on CPU load requirements.

Aftermarket Battery Packs - Revelations from Product Tear-Downs

Aftermarket battery packs are available for most portable devices. This webcast presents the results of several product tear-downs on aftermarket battery packs, and explains how substandard aftermarket packs can cut corners on cost, safety mechanisms, and battery performance. These tear-downs expose electronic & mechanical design issues, as well as good manufacturing and regulatory violations. Then, this webcast provides solutions for OEMs to manage and control their ecosystem of aftermarket battery pack suppliers. This webcast is applicable to OEMs of consumer and industrial electronic products susceptible to aftermarket batteries, such as medical, handheld radio, and data collection devices.
