eDesign Studio enables the engineer to create an application in four steps. Step 1: sign in. Step 2: select the type of power supply to be designed: AC/DC or DC/DC, LED lighting, photovoltaic DC/DC, or battery charger. Step 3: insert the input voltage, output voltage, and output current, and select one of the recommended ICs. Step 4: run the design. Most offline and DC/DC control ICs are in the online library at www.st.com/edesignsuite and more are being added continuously.
