ER2120QI

Overview

The ER2120QI is a discontinued Enpirion DC/DC step-down power module manufactured by Altera. It operates with an input voltage range of 5.5V to 14V and provides a single non-isolated output. The device delivers up to 2A of output current. It utilizes a synchronous buck converter topology for efficient power conversion. The component is designed for compact applications requiring integrated power management solutions.

Feature Summary

• Integrates a synchronous buck converter into a compact package
• Provides digital control capabilities for the power stage
• Features a wide input voltage range suitable for various bus voltages

Applications

• Validating Enpirion power device performance on evaluation boards
• Development of embedded systems requiring isolated or non-isolated DC-DC conversion
• Prototyping portable electronic devices with specific voltage regulation needs

Procurement Notes

Verify end-of-life status before design finalization, as this part is discontinued. Confirm that alternative components from the same family meet all electrical requirements. Check for available documentation such as user guides and PCB layout files to support migration efforts. Ensure compatibility with existing board designs if replacement is necessary.

Selection Notes

Select this component only if legacy system compatibility is required due to its discontinued status. Evaluate the availability of equivalent newer generation Enpirion modules for new designs. Consider the physical footprint and pinout compatibility when comparing against potential substitutes. Review thermal performance data to ensure adequate heat dissipation in the target application environment.

Part Context

The ER2120QI belongs to the Enpirion series of power solutions developed by Altera. This series focuses on integrating power MOSFETs, controllers, and inductors into a single package. The product line aims to simplify power supply design by reducing component count and board space requirements. Altera acquired the technology behind these modules to expand its portfolio beyond programmable logic devices.
