MB39C022NPN-G-EFE1

Overview

The MB39C022NPN-G-EFE1 is a dual-output power management IC from Infineon Technologies, integrating a synchronous buck converter and a linear regulator. It operates with an input voltage range of 2.5 V to 5.5 V. The buck section delivers up to 300 mA output current, while the linear regulator provides additional regulated voltage. Designed for low-noise applications, it features a switching frequency of 2 MHz. The device supports shutdown functionality and is housed in a compact 10-lead SON package suitable for surface-mount assembly.

Feature Summary

• Integrates a synchronous buck DC/DC converter and a linear regulator in a single package
• Supports system shutdown via dedicated control pin
• Optimized for low-noise performance in sensitive electronic circuits

Applications

• Portable consumer electronics requiring efficient power management
• Battery-powered devices needing dual voltage rails
• Embedded systems with strict noise sensitivity requirements

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm date codes and lot numbers against official documentation. Check for moisture sensitivity level compliance prior to soldering. Ensure storage conditions meet specified humidity restrictions to prevent package damage during handling and assembly processes.

Selection Notes

Select this IC when a combined buck and LDO solution is required within a small footprint. Consider the 2 MHz switching frequency for EMI management and passive component size reduction. Evaluate thermal performance based on expected load currents and ambient operating temperatures. Verify input voltage compatibility with the 2.5 V to 5.5 V operational range before integration into the design.
