Overview

The FAN23SV04T is a highly efficient, integrated synchronous buck regulator for use in tracking applications, such as DDR termination rails. The VDDQ input includes an internal 2:1 resistive voltage divider to reduce total circuit size and component count. The regulator operates with an input range from 7 V to 18 V and supports up to 4 A load currents. The device can operate from a 5 V rail (±10%) if VIN, PVIN, and PVCC are connected together to bypass the internal linear regulator.
This device utilizes ON Semiconductor’s constant on-time control architecture to provide excellent transient response and to maintain a relatively constant switching frequency.
Switching frequency and sourcing over-current protection can be programmed to provide a flexible solution for various applications.
Output over-current, and thermal shutdown protections help prevent damage during fault conditions. A hysteresis feature restarts the device when normal operating temperature is reached.

  • This product is general usage and suitable for many different 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.)
