NCP81151MNTBG

The NCP81151MNTBG is a VR12.5 compatible synchronous buck MOSFET driver in 8 pin DFN package. This 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 systems. The UVLO function guarantees the outputs are low when the supply voltage is low. It is used in power management solutions for notebook systems.

• Supply voltage range from -0.3V to 6.5V
• Faster rise and fall times
• 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 compatible PWM controllers
• Thermally enhanced package
