Integrated Driver with High-Side and Low-Side MOSFETs

Favorite

Overview

The NCP81081 integrates a MOSFET driver, high side MOSFET and low side MOSFET into a 6 mm x 6 mm 40-pin QFN package. The driver and MOSFETs have been optimized for high current DC to DC buck power conversion applications. The NCP81081 integrated solution greatly reduces package parasitics and board space compared to a discrete component solution.

  • Capable of switching frequencies up to 1 MHz
  • Capable of output currents up to 35 A
  • PWM input capable of 3.3 V and 5 V
  • Internal bootstrap diode
  • Zero current detection
  • VCIN undervoltage lockout
  • Internal thermal warning / thermal shutdown
