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.
1 40
The driver and MOSFETs 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
