Overview

The NCP81149, a single-phase synchronous buck regulator, integrates power MOSFETs to provide a high-efficiency and compact-footprint power management solution for new generation computing CPUs. The device is able to deliver up to 14A TDC output current on an adjustable output with SVID interface. Operating in high switching frequency up to 1.2MHz allows employing small size inductors and capacitors while maintaining high efficiency due to integrated solution with high performance power MOSFETs. Current-mode RPM control with feedforward from both input power supply and output voltage ensures stable operation over wide operation condition. The NCP81149 is in a QFN48 6x6mm package.

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.)
