• Manufacturer Part Number: ncv8871
• Description: Ncv8871 Automotive Grade Non-synchronous Boost Controller
• Manufacturer: ON Semiconductor

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
*An external diode from the input to the VIN pin is required if bootstrapping VDRV and VIN off of the output voltage.
