FAN21SV06EMPX

Overview

The FAN21SV06EMPX is a TinyBuck integrated synchronous buck regulator manufactured by onsemi. It features a single input voltage range up to 24V and delivers an adjustable output current of 6A. The device utilizes a constant on-time control architecture with integrated power MOSFETs. It operates within a temperature range of -40°C to +85°C and is housed in a 25-lead MLP package.

Feature Summary

• Integrates synchronous buck topology with internal power switches for compact design
• Supports synchronization capability for multi-phase or parallel applications
• Utilizes constant on-time control architecture for wide load current ranges

Applications

• Industrial point-of-load regulation
• Embedded system power distribution
• Communication equipment bias supplies

Procurement Notes

Verify the specific suffix EMPX against the manufacturer datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure the ordering part number matches the required lead-free and RoHS compliance status defined in the official component documentation before finalizing procurement.

Selection Notes

Select this component when a 6A synchronous buck solution with 24V input capability is required. The integrated MOSFETs simplify thermal management compared to discrete designs. Verify that the application requires synchronization features if multiple regulators are used in close proximity.

Part Context

This part belongs to the TinyBuck family of integrated switching regulators from onsemi. The series combines high efficiency with a small footprint by integrating the controller and power stage into a single package, targeting dense power conversion needs in modern electronics.
