NCP81081
Integrated Driver and
MOSFET
The NCP81081 integrates a MOSFET driver , highside MOSFET
and lowside MOSFET into a 6 mm x 6 mm 40 pin QFN package.
The driver and MOSFET s have been optimized for highcurrent
DCDC 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 PbFree Devices
