MB39C316PW-G-ERE1

Overview

The MB39C316PW-G-ERE1 is a PMIC voltage regulator from Infineon Technologies featuring seven output channels. It integrates two synchronous step-down (buck) converters, one buck/boost converter, and four linear regulators (LDOs). The device utilizes a 49-ball WLCSP package for compact integration. This multi-output architecture supports complex power sequencing requirements in portable electronics by combining switching efficiency with low-noise linear regulation capabilities.

Feature Summary

• Integrates multiple conversion topologies including synchronous buck, buck-boost, and LDO stages within a single IC
• Provides seven independent regulated outputs to support diverse voltage rails in system-on-chip designs
• Optimized for space-constrained applications through the use of a small footprint wafer-level chip scale package

Applications

• Portable consumer electronics requiring multi-rail power management
• Smartphones and mobile devices with complex power sequencing needs
• Tablets and handheld computing devices
• IoT modules with mixed analog and digital power requirements

Procurement Notes

Verify the specific suffix ERE1 against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB layout for the 49-ball WLCSP format. Check for any recent lifecycle status updates or alternative recommendations directly from Infineon official documentation before finalizing procurement plans.

Selection Notes

Select this component when a design requires seven distinct voltage rails from a single controller to minimize board space. It is suitable for systems needing both high-efficiency switching regulation and low-noise linear outputs. Consider the thermal performance of the WLCSP package relative to the total power dissipation of all seven channels during operation.

Part Context

This part belongs to the MB39C316 series of power management integrated circuits designed by Infineon Technologies. These components are engineered for high integration levels in portable devices. The series focuses on reducing external component counts while providing flexible power distribution architectures for modern mobile platforms.

Replacement Considerations

Consult Infineon official documentation for verified substitute part numbers. Do not assume cross-compatibility with other PMIC families without checking pinout and electrical parameter alignment.
