使用 Analog Devices 的 LTC1148 的參考設(shè)計(jì)

AN54, Application Circuit Using LTC1148 4-14 V, 3.3V/2A Buck Converter with Surface Mount Technology

設(shè)計(jì)簡介

AN54，采用采用表面貼裝技術(shù)的 LTC1148 4-14V、3.3V/2A 降壓轉(zhuǎn)換器的應(yīng)用電路。高效率通常是便攜式計(jì)算機(jī)和手持設(shè)備電源的主要目標(biāo)。在這些應(yīng)用中，高效的轉(zhuǎn)換器是必要的，以最大限度地減少輸入源（電池等）的功耗和功率組件的熱量積聚，從而實(shí)現(xiàn)更小、更輕和壽命更長的系統(tǒng)

說明

AN54, Application Circuit Using LTC1148 4-14 V, 3.3V/2A Buck Converter with Surface Mount Technology. High efficiency is frequently the main goal for power supplies in portable computers and hand-held equipment. Efficient converters are necessary in these applications to minimize power drain on the input source (batteries, etc.) and heat buildup in the power components, allowing for smaller, lighter, and longer-lived systems
