NCP81081
Integrated Driver and
MOSFET
The NCP81081 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 MOSFET s have been optimized for high−current
DC−DC buck power conversion applications. The NCP81081
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
• PWM Input Capable of 3.3 V and 5 V
• Internal Bootstrap Diode
• Zero Current Detection
• Undervoltage Lockout
• Internal Thermal Warning / Thermal Shutdown
• These are Pb−Free Devices
