High-frequency digital point-of-load converter using a 16 bits DSC.

This paper is focused on the design of a test-bank to develop high-frequency digital control laws for point-of-load converters. As a result, a high-frequency digital DC/DC converter prototype has been completed using a Freescalepsilas DSC as digital controller. During this exposition, we present the design guidelines to build this test-bank and how to adapt some state-of-the-art digital control laws for DC/DC converters working at high switching frequencies. Experimental results validate these digital control laws and the global converter behavior.
