FAN2356AMPX

Overview

The FAN2356AMPX is a synchronous buck regulator manufactured by onsemi, designed for high-efficiency power conversion in compact form factors. It delivers an output current of 6 A with an adjustable output voltage range from 600 mV to 5.5 V. The device operates within an input voltage window of 4.5 V to 24 V and supports switching frequencies between 200 kHz and 1.5 MHz. Key electrical characteristics include a quiescent current of 24 µA and an operating temperature range from -40°C to +125°C. It utilizes a PQFN-34 package.

Feature Summary

Integrated synchronous rectification for improved efficiency
Adjustable switching frequency for optimization
Compact surface-mount packaging

Applications

Industrial equipment power distribution
Consumer electronics DC-DC conversion
Telecommunications infrastructure power supplies

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm datasheet revisions match design requirements. Check RoHS compliance documentation. Validate package marking against official specifications. Ensure supply chain stability given discontinuation schedule.

Selection Notes

Evaluate thermal performance under maximum load conditions. Verify input voltage compatibility with system rails. Assess inductor selection for target ripple current. Consider PCB layout constraints for PQFN-34 footprint. Review transient response requirements for load steps.

Part Context

This component belongs to the FAN23xx series of synchronous buck regulators from onsemi. It shares architectural similarities with related models like the FAN2360AMPX but differs in output current capability. The series targets applications requiring efficient step-down conversion in space-constrained environments.
