ADP3118JRZ集成電路（IC）的柵極驅(qū)動(dòng)器規(guī)格書PDF中文資料

ADP3118JRZ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ADP3118JRZ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 ADP3118 is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, which are the two switches in a nonisolated synchronous buck power converter. Each of the drivers is capable of driving a 3000 pF load with a 25 ns propagation delay and a 25 ns transition time. One of the drivers can be bootstrapped and is designed to handle the high voltage slew rate associated with floating high-side gate drivers. The ADP3118 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs.

FEATURES

Optimized for low gate charge MOSFETs

All-in-one synchronous buck driver

Bootstrapped high-side drive

One PWM signal generates both drives

Anticross-conduction protection circuitry

Output disable control turns off both MOSFETs to float output per Intel VRM 10

Meets CPU VR requirement when used with Analog Devices, Inc. Flex-Mode1 controller

APPLICATIONS

Multiphase desktop CPU supplies

Single-supply synchronous buck converters
