Overview
The FAN2001MPX is a step-down switching regulator IC from onsemi, designed for high-efficiency power conversion. It features an adjustable output voltage range of 0.8V to 5.5V and supports a maximum output current of 1A. The device operates with an input voltage range of 2.5V to 5.5V. Packaged in a compact 6-MLP (3x3) format, it integrates internal compensation and protection features suitable for space-constrained applications requiring stable DC-DC regulation.
Feature Summary
- Integrates a high-efficiency synchronous buck converter topology
- Provides adjustable output voltage control via external feedback network
- Includes built-in soft-start functionality to limit inrush current
- Features comprehensive protection mechanisms including thermal shutdown
Applications
- Portable battery-powered consumer electronics
- Industrial control systems requiring regulated low-voltage rails
- Embedded computing modules and single-board computers
- Communication equipment power distribution networks
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and temperature grade specifications. Confirm that the 6-MLP package dimensions align with your PCB footprint requirements. Cross-reference the part number with official distributor catalogs to validate authenticity and avoid counterfeit components during sourcing.
Selection Notes
Select this component when a compact, high-efficiency solution is required for stepping down voltages within the 2.5V to 5.5V input range. It is appropriate for designs needing up to 1A continuous output current with minimal external passive components. Consider thermal management capabilities if operating near maximum load conditions in enclosed environments.
Part Context
This part belongs to onsemi's portfolio of switching voltage regulators, specifically targeting applications where size and efficiency are critical constraints. It complements other PMIC solutions by offering a simple, cost-effective approach to DC-DC conversion without complex external control loops or extensive peripheral circuitry.
Replacement Considerations
Consult official cross-reference guides for direct pin-compatible alternatives. Verify electrical parameter compatibility, particularly input/output voltage ranges and current limits, before substituting with similar step-down converters from other manufacturers.
