MB39C022GPN-G-EFE1

Overview

The MB39C022GPN-G-EFE1 is a dual-output power management IC from Infineon Technologies, integrating a synchronous buck converter and a low-noise LDO. It operates with an input voltage range of 2.5 V to 5.5 V. The buck channel provides up to 600 mA output current at 3.3 V, while the LDO supports adjustable outputs from 800 mV to 4.5 V. Operating at a fixed switching frequency of 2 MHz, it utilizes a 10-WFDFN exposed pad package. The device functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a synchronous step-down DC/DC converter with a dedicated low-dropout linear regulator in a single compact package.
• Features a high switching frequency of 2 MHz to minimize external component size while maintaining stable regulation.
• Includes shutdown functionality for effective power management and energy conservation in portable applications.

Applications

• Portable electronic devices requiring efficient multi-rail power distribution
• Battery-powered systems needing combined switching and linear regulation
• Embedded circuits utilizing 2.5 V to 5.5 V input supply rails

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeits. Confirm RoHS compliance status via official documentation before integration. Check for moisture sensitivity classification requirements during storage and handling. Ensure the specific suffix matches design specifications as variants may differ electrically or mechanically.

Selection Notes

Select this component when space constraints require combining buck and LDO functions. Suitable for designs needing a high-current switching rail alongside a clean, adjustable linear supply. Evaluate thermal performance given the small footprint and power dissipation limits. Compare against single-function regulators if board area allows for separate components.

Part Context

This part belongs to the MB39C022 series of PMICs designed for mobile and handheld applications. It addresses the need for integrated power solutions that reduce bill-of-materials count. Similar models in the family may offer different output currents or fixed voltage options but share the same functional architecture.

Replacement Considerations

Direct substitutes include other Infineon MB39C022 variants such as MB39C022GPN-G-ERE1, which shares the same core topology and pinout configuration. Verify electrical parameters match specific design requirements before substitution.
