ADP3415集成電路（IC）的柵極驅(qū)動(dòng)器規(guī)格書PDF中文資料

ADP3415屬于集成電路（IC）的柵極驅(qū)動(dòng)器。由安森美半導(dǎo)體公司制造生產(chǎn)的ADP3415柵極驅(qū)動(dòng)器柵極驅(qū)動(dòng)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(hào)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(dòng)的半導(dǎo)體配置相關(guān)。

GENERAL DESCRIPTION

The ADP3415 is a dual MOSFET driver optimized for driving two N-channel FETs that are the two switches in the nonisolated synchronous buck power converter topology. Each driver size is optimized for performance in notebook PC regulators for CPUs in the 20 A range. The high-side driver can be bootstrapped atop the switched node of the buck converter as needed to drive the upper switch and is designed to accommodate the high voltage slew rate associated with high performance, high frequency switching. The ADP3415 features an overlapping protection circuit (OPC); undervoltage lockout (UVLO) that holds the switches off until the driver is assured of having sufficient voltage for proper operation; a programmable transition delay; and a synchronous drive disable pin. The quiescent current, when the device is disabled, is less than 100 μA.
