Overview
The EN2342QI is a non-isolated Point-of-Load (PoL) module DC-DC converter belonging to the Enpirion PowerSoC series. It operates with an input voltage range of 4.5 V to 14 V and provides a single adjustable output voltage from 750 mV to 5 V. The device supports a maximum output current of 4 A, delivering up to 20 W of power. It utilizes a buck topology with a switching frequency of 1 MHz. The component is housed in a 68-BFQFN package with dimensions of 11.0 mm x 8.0 mm x 3.0 mm.
Feature Summary
- Integrates controller, power switches, and passive components into a single PowerSoC module for compact design.
- Includes remote on/off control capability for system power management.
- Provides comprehensive protection features including overcurrent, overtemperature, short circuit, and undervoltage lockout.
Applications
- Information Technology Equipment (ITE)
- Commercial electronic systems
- Point-of-load voltage regulation
Procurement Notes
Verify availability status as the EN2342QI has reached end-of-life. Confirm final procurement through authorized channels or approved distributors before initiating orders. Check for valid replacement part numbers if active sourcing is required. Ensure compliance with RoHS specifications and moisture sensitivity level requirements during handling and storage procedures.
Selection Notes
Select this component for applications requiring high-density power conversion with minimal external component count. The wide input voltage range suits various bus architectures. Consider the thermal performance within the specified operating temperature range of -40°C to +85°C. Evaluate board space constraints against the small QFN footprint for optimal integration.
Part Context
This device is part of the Altera Enpirion PowerSoC family, designed to simplify power supply design by integrating all necessary elements into one package. It replaces traditional discrete solutions, reducing assembly complexity and improving reliability. The product line focuses on efficient, high-power-density DC-DC conversion for modern electronic devices.
Replacement Considerations
The EN2342QI is discontinued. Verify specific alternative part numbers from official manufacturer documentation or authorized distributor databases for direct functional replacements.
