Overview
NCP5338 Integrated Driver and MOSFET The NCP5338 integrates a MOSFET driver, high−side MOSFET and low−side MOSFET into a 6 mm x 6 mm 40−pin QFN package.
The driver and MOSFETs have been optimized for high−current DC−DC buck power conversion applications.
The NCP5338 integrated solution greatly reduces package parasitics and board space compared to a discrete component solution.
Features • Optimized for High Frequency, High Conversion Ratio Operation • Capable of Switching Frequencies Up to 1.
5 MHz • Internal Bootstrap Diode • Zero Current Detection • Undervoltage Lockout • Internal Thermal Warning / Thermal Shutdown • 40 A Continuous Output Current Capability • These are Pb−Free Devices 5 V 12−20 V 5V ZCD Enable Output Disable PWM Thermal Warning THWN VIN VCIN BOOT ZCD_EN# DISB# PWM CGND PHASE VSWH PGND Vout http://onsemi.
