APPLICATION INFORMATION
The design shown in this application information is a reference design for a notebook PC application. An
evaluation module (EVM) is available for customer testing and evaluation. This information allows a customer
to fully evaluate the given design using the plug-in EVM shown in Figure17. For subsequent board revisions,
the EVM design can be copied onto the system PCB to shorten the design cycle.
The following key design procedures aid in the design of the notebook PC power supply using TPS5110. An
optional circuit composed of Q04, R16, R22 and R24 can be used to increase temperature coefficient of the
trip current, which is at the top in the page 18.
