Overview
The FAN23SV56AMPX is a synchronous buck regulator manufactured by onsemi, housed in a PQFN-34 package. It delivers an output current of 6 A with an adjustable voltage range from 600 mV to 5.5 V. The device operates within an input voltage window of 7 V to 24 V and supports switching frequencies between 200 kHz and 1.5 MHz. Key electrical specifications include a quiescent current of 24 uA and an operating temperature range spanning -40°C to +125°C.
Feature Summary
- Synchronous rectification for improved efficiency
- Adjustable output voltage capability
- Wide input voltage tolerance
- Integrated shutdown control
Applications
- Industrial power systems
- Telecommunications infrastructure
- Enterprise server platforms
Procurement Notes
Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm package integrity and pin alignment against the official datasheet before integration. Ensure supply chain stability as manufacturing may be discontinued. Validate compliance with RoHS and REACH standards required for target markets.
Selection Notes
Select this regulator when a 6 A synchronous buck solution is required for inputs up to 24 V. The wide frequency range allows optimization for size or noise. Verify thermal management requirements for the PQFN-34 package under maximum load conditions. Compare against the FAN2306AMPX if lower input voltage ranges are sufficient for the design.
Part Context
This component belongs to the FAN23xx series of high-efficiency synchronous buck regulators from onsemi. It shares architectural similarities with the FAN2306AMPX but differs in input voltage specifications. The series targets compact power designs requiring high current density and low standby consumption in space-constrained applications.
Replacement Considerations
The FAN2306AMPX serves as a functional substitute within the same product family. Both share identical output current, package type, and control features. Designers must verify that the lower maximum input voltage of the FAN2306AMPX aligns with system requirements.
