Abstract :
This paper presents the design and measurements of a dual output voltage (3.3 V and 2.5 V) quarter-brick DC/DC converter for telecom applications. Secondary-side control is used since outputs must be trimmable and must have very good regulation capabilities. Control architecture is analyzed in detail since the secondary-side control makes more complex other control functions (protections, start-up, etc.)
