NCP81145 Datasheet | onsemi

VR12.5 patible Synchronous Buck MOSFET Driver The NCP81145 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 3 n F load with a 25 ns propagation delay and 20 ns transition time. Adaptive anti- cross- conduction and power saving operation circuit can provide a low switching loss and high efficiency solution for notebook systems. The UVLO function guarantees the outputs are low when the supply voltage is low. Features - Faster Rise and Fall Times - Adaptive Anti- Cross- Conduction Circuit - Zero Cross Detection function - Output Disable Control Turns Off Both MOSFETs - Undervoltage Lockout - Power Saving Operation Under Light Load Conditions - Direct Interface to NCP6131 and Other patible PWM Controllers - Thermally Enhanced Package - These Devices are Pb- Free, Halogen Free/BFR Free and are Ro HS pliant Typical Applications - Power Management Solutions for Notebook systems http://onsemi.
