Additional Information

Several additional resources are available to make system

design with the CS5305 a simpler task. The power supply

designer is invited to obtain the following documents and

files from ON Semiconductor.

1.AND8045/D, “Enhanced V2 Multiphase SMPS for

Microprocessor.” This application note provides

details on the theory of operation, selection of

components,

layout

practices

and

thermal

management strategies necessary to design power

supplies with the CS5305 controller.

2.“Excel Spreadsheet Method for Choosing CS5305

External Components”. This Excel spreadsheet that

can be used to generate a first−pass schematic design

for VRM 9.x designs based on user input, and is

available from the factory.

3.“Excel Spreadsheet Method for CS5305 Power Budget

Optimization”. This Excel spreadsheet that can be

used to calculate power dissipation in all the

high−power dissipation components (including metal

traces). This allows the design to be optimized for

power/thermal management, and is available from the

factory.
