  • The NCP81253 is a high-performance dual MOSFET gate driver in a small 2 mm x 2 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 NCP81253 comes packaged with an integrated boost diode to minimize the number of external components. A VCC UVLO function guarantees the outputs are low when the supply voltage is low.
  • Features
  • Internal bootstrap diode - Reduces number of external components
  • 5 V 3-stage PWM input - Allows for high-impedance state
  • Adaptive anti-cross-conduction circuit - Protects against cross-conduction during FET turn-on and turn-off
  • Diode braking capability - Quickly reduces inductor current
  • Output disable control - Ability to turn off both MOSFETs via the Enable pin
  • VCC undervoltage lockout - Guarantees outputs are low when supply voltage is low
  • Applications
  • Power solutions for notebook and desktop systems
