LM5170-Q1: The LM5170-Q1 Design Calculator

Nantawat Thitichaiworakorn

Part Number: LM5170-Q1

Hello.

Could anyone explain me what are the calculations of the type-II compensators behind the LM5170-Q1 Design Calculator for both current loop and voltage loop (in boost mode) ? What are the plants' transfer functions and what are the loop gains ? Could anyone send me or suggest me any documents for reading ?

Thanks.

Hi Nantawat,

Please take a look at this training material. This explains how the average current mode loop is modeled and some examples on how to compensate the loops correctly.

Thanks,
