MB39C022JPN-G-EFE1

Overview

The MB39C022JPN-G-EFE1 is a dual-output power management IC from Infineon Technologies, integrating one synchronous step-down (Buck) converter and one low-dropout (LDO) linear regulator. It operates with an input voltage range of 2.5 V to 5.5 V. The Buck output provides adjustable voltage between 0.8 V and 4.5 V with a switching frequency of 2 MHz. The device is housed in a 10-lead SON package.

Feature Summary

• Integrates a synchronous buck converter and a linear regulator in a single compact package
• Supports wide input voltage range for flexible system design
• Features high-frequency switching for reduced external component size

Applications

• Portable electronic devices requiring multiple voltage rails
• Battery-powered systems needing efficient DC/DC conversion
• Embedded applications with space-constrained PCB layouts

Procurement Notes

Verify current availability status as the component may be discontinued or subject to supply constraints. Confirm exact ordering suffixes match required specifications. Check RoHS compliance documentation for regulatory adherence. Validate pin compatibility if replacing existing designs. Consult official distributors for lead time estimates.

Selection Notes

Select this IC when a combined buck and LDO solution is needed to save board space. Ensure input voltage stays within 2.5 V to 5.5 V limits. Verify that the 2 MHz switching frequency aligns with EMI requirements. Consider thermal performance in the 10-SON package for high-current applications.
