ADI公司的DAuM5010是一款雙通道內(nèi)部集成數(shù)字隔離DC-DC轉(zhuǎn)換控制器。基于ADI公司先進(jìn)iCoupler® 技術(shù)，數(shù)字隔離DC-DC轉(zhuǎn)換控制器提供隔離調(diào)整電壓范圍：3.15-5.25V，輸入電壓的范圍可以從供給略低于所需的輸出來(lái)顯著提高。本文介紹了DAuM5010芯片的主要特性、方框圖、應(yīng)用方向。評(píng)估板EVAL-ADuM5010EBZ的主要特性、電路圖、材料清單和PCB元件布局圖。
The ADuM50101 is an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides regulated, isolated power, adjustable between 3.15 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popular combinations and their associated power levels are shown in Table 1 .
The iCoupler chip-scale transformer technology is used for isolated logic signals and for the magnetic components of the dc-to-dc converter. The result is a small form factor, total isolation solution.
isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. See the AN-0971 Application Note for board layout recommendations.
