Overview

NCP3136 is a fully integrated synchronous buck converter for 3.3 V and 5 V step−down applications. It can provide up to 6.5 A instantaneous current. NCP3136 supports high efficiency, fast transient response and provides power good indicator. The control scheme includes two operation modes: FCCM and automatic CCM/DCM. In automatic CCM/DCM mode, the controller can smoothly switch between CCM and DCM, where converter runs at reduced switching frequency with much higher efficiency. NCP3136 is available in 3 mm x 3 mm QFN16 pin package.

  • 5V and 3.3V POL applications

  • servers/desktops/notebooks
  • solid state drives
  • base station/networking

  • Automatic DCM/CCM and FCCM operating modes
  • 1.1MHz Switching Frequency
  • 3mm by 3mm QFN package
  • Output range from 0.6V to 0.84Vin
  • Over/Undervoltage, Overcurrent, and Overtemperature protection
  • Internal 1.5ms soft start
  • Safe start up into prebias output
  • Up to 5A continuous current
  • hiccup mode during short circuit conditions

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.)
