FAN2108MPX

Overview

The FAN2108MPX is an 8A, 24V synchronous buck regulator manufactured by onsemi. It integrates high-side and low-side N-channel power MOSFETs with a fixed-frequency current-mode control architecture. The device operates from a 4.5V to 24V input supply range and delivers up to 8A of output current. It features adjustable switching frequency, programmable soft-start, and comprehensive protection mechanisms including over-current, over-voltage, and thermal shutdown. The component is available in a compact 6-lead MicroFET package.

Feature Summary

Integrates dual N-channel power MOSFETs for efficient synchronous rectification
Fixed-frequency current-mode control architecture for stable operation
Includes programmable soft-start functionality to limit inrush current
Provides integrated protection against over-current, over-voltage, and thermal faults

Applications

Point-of-load (POL) voltage regulation for digital logic
Power distribution networks in embedded systems
Voltage conversion for communication equipment
Industrial control system power supplies

Procurement Notes

Verify the specific suffix 'MPX' corresponds to the intended tape-and-reel packaging configuration as defined in the official datasheet. Confirm that the ordering part number matches the exact pinout and thermal pad requirements for the target PCB layout. Ensure compliance with RoHS directives and check for any recent product change notices affecting material composition or manufacturing location before finalizing procurement.

Selection Notes

Select this regulator when an 8A output current capability and a maximum 24V input voltage are required. Consider the fixed switching frequency and current-mode control characteristics for noise-sensitive applications. Evaluate the thermal performance within the 6-lead MicroFET package against the expected ambient temperature and load conditions. Verify compatibility with the desired output voltage setting and soft-start timing requirements for the system power-up sequence.

Part Context

The FAN2108 belongs to onsemi's family of synchronous buck regulators designed for medium-current applications. It complements other devices in the series offering different current ratings or input voltage ranges. The MPX suffix typically denotes a specific reel quantity and packaging variant suitable for automated surface-mount assembly processes, distinguishing it from cut-tape or bulk packaging options.
