ADP3419JRM-REEL集成電路（IC）的柵極驅(qū)動器規(guī)格書PDF中文資料

ADP3419JRM-REEL屬于集成電路（IC）的柵極驅(qū)動器。由安森美半導(dǎo)體公司制造生產(chǎn)的ADP3419JRM-REEL柵極驅(qū)動器柵極驅(qū)動器電源管理集成電路 (PMIC) 可用于提供隔離、放大、參考位移、自舉或其他必要功能，這些功能可將來自電源轉(zhuǎn)換應(yīng)用中控制設(shè)備的信號連接到電源被控制通過的半導(dǎo)體設(shè)備（通常為 FET 或 IGBT）。任何特定設(shè)備提供的確切功能各不相同，但與它適合驅(qū)動的半導(dǎo)體配置相關(guān)。

The ADP3419 is a dual MOSFET driver optimized for driving two N-channel switching MOSFETs in nonisolated synchronous buck power converters used to power CPUs in portable computers. The driver impedances have been chosen to provide optimum performance in multiphase regulators at up to 25 A per phase. The high-side driver can be bootstrapped relative to the switch node of the buck converter and is designed to accommodate the high voltage slew rate associated with floating high-side gate drivers.
