Product Overview NCP81146: VR12.5 Buck MOSFET Driver For complete documentation, see the data sheet Product Description The NCP81146 is a high performance dual MOSFET gate driver optimized to drive the gates of both high-side and low-side power MOSFETs in a synchronous buck converter. It can drive up to 3nF load with a 25ns propagation delay and 20ns transition time. Adaptive anti-cross-conduction and power saving operation circuit can provide a low switching loss and high efficiency solution for notebook and desktop systems. Bidirectional EN pin can provide a fault signal to controller when the gate driver fault detect under OVP, UVLO occur. Also, an undervoltage lockout function guarantees the outputs are low when supply voltage is low Features • • • • • • • • • Faster rise and fall times Adaptive anti-cross-conduction circuit Integrated bootstrap diode Pre OV function ZCD detect Floating top driver accommodates boost voltages of up to 35V Output disable control turns off both MOSFETs Under-voltage lockout Power saving operation under light load conditions Applications • Industrial based power applications Part Electrical Specifications Product Compliance Status Type NCP81146MNTBG Pb-free Active MOSFET Number of Drivers Vin Max (V) VCC Max (V) Drive Source/Si nk Typ (mA) 13.2 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
