Overview

The FAN21SV04 is a highly efficient, small-footprint, programmable-frequency, 4A, integrated synchronous buck regulator.FAN21SV04 contains both synchronous MOSFETs and a controller/driver with optimized interconnects in one package, which enables designers to solve high-current requirements in a small area with minimal external components, thereby reducing cost. On-board internal 5V regulator enables single-supply operation for input voltages >6.5V.The FAN21SV04 can be configured to drive multiple slave devices OR synchronize to an external system clock. In slave mode, FAN21SV04 may be set up to be free-running in the absence of a master clock signal.External compensation, programmable switching frequency, and current-limit features allow for design optimization and flexibility. High-frequency operation allows for all-ceramic solutions.onsemi’s advanced BiCMOS power process, combined with low-RDS(ON) internal MOSFETs and a thermally efficient MLP package, provide the ability to dissipate high power in a small package. Integration helps minimize critical inductances, making layout simpler and more efficient compared to discrete solutions.Output over-voltage, under-voltage, over-current, and thermal-shutdown protections help protect the device from damage during fault conditions. FAN21SV04 prevents pre-biased output discharge during startup in point-of-load applications.

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.)
