EN6310QA

Overview

The EN6310QA is a 1A PowerSoC synchronous step-down converter from the Altera Enpirion series. It integrates the controller, power switches, and inductor into a single package. The device operates with an input voltage range of 2.4 V to 6 V. It provides an adjustable output voltage from 0.6 V to 3.3 V. The unit supports a switching frequency of 2.2 MHz. It is housed in a 30-lead QFN package with an exposed pad. The component is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

Integrates synchronous PWM buck controller, power MOSFETs, and inductor within a single compact package.
Designed for high efficiency using voltage mode control architecture.
Qualified to AEC-Q100 automotive reliability standards.

Applications

Automotive electronic systems requiring AEC-Q100 compliance
Point-of-load regulation for digital logic supplies
Industrial equipment power distribution

Procurement Notes

Verify current availability status as the component is listed as obsolete or discontinued by the manufacturer. Confirm that any available stock represents original manufacturer inventory rather than third-party surplus. Ensure the specific suffix matches the required operating temperature grade and packaging format before finalizing procurement decisions.

Selection Notes

Select this component when a compact solution integrating the inductor is required for space-constrained designs. Consider the 2.2 MHz switching frequency for smaller external capacitor requirements. Verify that the 1A output current meets the load demands. Check compatibility with the 2.4 V to 6 V input supply range.

Part Context

This part belongs to the Enpirion PowerSoC family, which combines multiple power management functions into one integrated circuit. The EN6310QA specifically targets applications needing efficient DC-DC conversion without the footprint of discrete components. It serves as a drop-in replacement for larger multi-component buck regulator designs.
