NCP5369
Integrated Driver and MOSFET
The NCP5369 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 NCP5369 integrated solution greatly reduces package parasitics and board space compared to a discrete component solution.
Features
• Capable of Switching Frequencies Up to 1 MHz • Capable of Output Currents Up to 35 A • Internal Bootstrap Diode • Zero Current Detection • Undervoltage Lockout • Internal Thermal Warning / Thermal Shutdown • These are Pb−Free Devices
