Overview

The NCP81152 is a high-performance dual MOSFET gate driver optimized to drive the gates of both high-side and low-side power MOSFETs in a synchronous buck converter. Two drivers are co-packaged into a 2.5 mm x 3.5 mm QFN16 package that greatly reduces the footprint compared to two discrete drivers. Adaptive anti-cross-conduction circuitry and power saving operation provides a low-switching-loss and high-efficiency solution. The under-voltage lockout function guarantees the outputs are low when the supply voltage is low.

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.)
