When the switch software is turned on, energy is stored in the inductor L and the inductor current iL ramps up at a slope determined by the input voltage. Diode D is off during this period. Once the switch, SW, turns off, diode D starts to conduct and the energy stored in the inductor is released to the load. Current in the inductor ramps down at a slope determined by the difference between the input and output voltages.\u003c\/p\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47209384738988,"sku":"G165","price":12.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/G165A.jpg?v=1789451845","url":"https:\/\/dotfry.com\/products\/low-cost-boost-converter-3-3v-input-5v-output-at-250ma","provider":"dotfry","version":"1.0","type":"link"}
