information online 

now even faster 

Get relevant power management information fast and 

easy at TI’s power.ti.com website. 

Product and technical information, including datasheets 

and samples, are only a click away. No matter how a 

designer is approaching a problem, or his level of powermanagement- 

design expertise, the power.ti.com site 

can help find the right part. The site’s power management 

device locator conducts searches based on common 

industry language. Products can also be found based on 

a parametric search or through a quick search for TI 

device numbers. 

Also, with a navigation bar throughout, jumping between 

pages is easy, eliminating having to use the “back” button. 

The power.ti.com site can be personalized with a “My 

Workspace” area, saving the user’s desired key elements 

and documents for future reference. Other resources 

include a comprehensive selection of online power management 

training sessions, high-end design calculators 

and an “Ask an Expert” button available from every page.
