Product Overview NCP81062: Synchronous Buck MOSFET Driver For complete documentation, see the data sheet Product Description The NCP81062 is a high-performance MOSFET gate driver in a 3 mm x 3 mm packaged, optimized to drive the gates of both highside and low-side power MOSFETs in a synchronous buck converter. Zero current detect feature allows for a high-efficiency solution even at light load conditions. Pre-OVP feature aids in protecting the load in the event of a short across the high-side FET. VCC UVLO ensures the MOSFETs are off when supply voltages are low. A bi-directional Enable pin provides a fault signal to the controller when a pre-OVP or UVLO fault is detected. Features Benefits • Adaptive Anti-Cross-Conduction • • • • • Protects against cross-conduction during FET turn-on and turn-off • Minimizes external component count • Provides power saving operation during light load conditions • A single signal places the output into a high-impedance state • Ensures all MOSFETs are in off-state when supply voltages are low • Aids in protecting load during HS FET short • Provides a fault signal to the controller when a preOVP or UVLO fault is detected Integrated bootstrap diode Zero Cross Detection Output disable turns off both MOSFETs Under-Voltage Lockout • PreOVP • Bi-directional Enable • Pb-Free, Halogen/BFR Free and RoHS compliant Applications End Products • Vcore Power Subsystems • Desktop and Notebook Systems • Server Applications Part Electrical Specifications Product Compliance Status Type Number of Drivers Vin Max (V) VCC Max (V) NCP81062MNTWG Pb-free Active MOSFET 2 35 15 Drive Source/Si nk Typ (mA) Halide free For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016 Rise Time (ns) Fall Time (ns) 16 11 tp Max (ns) Package Type DFN-8
