NCP81081
Integrated Driver and
MOSFET
The NCP81081 integrates a MOSFET driver, highâside MOSFET
and lowâside MOSFET into a 6 mm x 6 mm 40âpin QFN package.
The driver and MOSFETs have been optimized for highâcurrent
DCâDC 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 PbâFree Devices
