EC2630QI

Overview

The Altera EC2630QI is a high-density DC-DC mid-voltage bus converter belonging to the Enpirion series. It functions as a charge pump switching regulator IC with synchronous rectification, designed for surface mount installation in a 36-VFQFN package with an exposed pad. The device accepts an input voltage range of 8V to 13.2V and provides a fixed positive output configured at Vin/2. It supports a maximum output current of 4.5A with a switching frequency of 115kHz. Operating within a temperature range of -40°C to 85°C, it is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Integrates synchronous rectification and charge pump topology for efficient power conversion
• Tracks input voltage to provide a regulated Vin/2 output suitable for multi-stage systems
• Designed for compact PCB layouts by eliminating common double-stage power conversion losses

Applications

• Mid-voltage bus conversion for 12V input systems
• Pre-regulation stage for downstream low-voltage load point converters
• High-efficiency power distribution in dense electronic assemblies

Procurement Notes

Verify component status carefully as this part is officially listed as End-of-Life (EOL). Check specific manufacturer notifications for discontinuation dates and last-time buy windows. Ensure compatibility with existing board designs before sourcing alternatives, as lead times may be unavailable or restricted due to the discontinued status.

Selection Notes

Select this component when a fixed half-input voltage regulation is required from a 12V nominal source. It is appropriate for applications prioritizing reduced PCB area and simplified design over adjustable output voltages. Consider the 36-VFQFN package constraints and thermal requirements for the exposed pad during layout planning.

Part Context

Part of the Altera Enpirion family of integrated power solutions. This specific model serves as a bus converter rather than a direct load-point regulator, intended to feed multiple lower-voltage converters efficiently. It complements other Enpirion devices in complete 12V solution architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative components must be evaluated based on electrical equivalence and pin compatibility through independent engineering analysis.
