DATA SHEET www.onsemi.com Synchronous Buck MOSFET Driver NCP81158D The NCP81158D is a high−performance dual MOSFET gate driver in a small 3 mm x 3 mm package, optimized to drive the gates of both high−side and low−side power MOSFETs in a synchronous buck converter. The driver outputs can be placed into a high−impedance state via the tri−state PWM and EN inputs. The NCP81158D comes packaged with an integrated boost diode to minimize external components. A VCC UVLO function guarantees the outputs are low when the supply voltage is low. Features • When Device is Powered, Fast PWM Response to EN Going High • Space−efficient 3 mm x 3 mm DFN8 Thermally−Enhanced Package • VCC Range of 4.5 V to 5.
