Overview

The NCP81391/A integrates a MOSFET driver, high−side MOSFET and low−side MOSFET into a single package. The driver and MOSFETs have been optimized for high−current DC−DC buck−boost power conversion applications. The NCP81391/A integrated solution greatly reduces package parasitics and board space compared to a discrete component solution.

  • Buck-Boost
  • Brushless DC

  • E−Cigarettes
  • Unmanned Aerial Vehicles (Drones)

  • Capable of Average Currents up to 25 A
  • Capable of Peak Currents up to 65 A
  • Over 97% Peak−Efficiency
  • Compatible with 3.3 V and 5 V PWM Inputs, with Tri−State
  • Zero Current Detection for Improving Light Load Efficiency
  • Thermal Shutdown
  • Internal Bootstrap Diode
  • Undervoltage Lockout

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
