In this talk I will talk about step-down (buck) and step-up (boost) converters, covering the basics in an easy-to-understand form, and touching on the knowledge you need to build your own.\n\nThis talk will be enjoyable for you if you have basic electronics knowledge: you understand what voltage, resistance, and current mean.\n\n##Outline\n- Theory of operation explained with illustrations\n- Synchronous and asynchronous converters: advantages and disadvantages\n- How to chose and evaluate cheap DC/DC converter modules you can buy online\n- Efficiency and sources of energy loss\n- Features you might want: Enable, Current Limiting, Undervoltage Protection\n- Control modes: voltage mode, current mode, and hysteretic mode\n- Unstable converters, and how to fix them\n- Switching noise, and how to deal with it\n- What if you need more voltage? Boost converters!","original_language":"eng","persons":["Zoé Bőle"],"tags":["36c3-chaoswest","134","2019","Nicht
