VR12.5 Synchronous Buck MOSFET Driver

Description

The NCP81158 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 NCP81158 comespackaged with an integrated boost diode to minimize external components. A VCC UVLO function guarantees the outputs are low when the supply voltage is low.
