Overview

The NCP3237 is a single−phase synchronous buck converter that integrates power MOSFETs to provide a high−efficiency and compact−footprint power management solution. This device is able to deliver up to 8 A output current over a wide output voltage range from 0.6 V to 12 V (up to 80% of VIN). The NCP3237 offers a fixed frequency regulator ideally suited for noise sensitive systems.

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.)
