MOSFET Driver Compatible with Single-Phase IMVP8 Controllers

Favorite

Overview

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.

  • Power solutions for notebook and desktop systems
  • Internal bootstrap diode
  • 5 V 3-stage PWM input
  • Adaptive anti-cross-conduction circuit
  • Diode braking capability
  • Output disable control
  • VCC undervoltage lockout
