MIC2807-MMYML

Overview

The MIC2807-MMYML is a power management integrated circuit manufactured by Microchip Technology, formerly Micrel. It integrates a high-performance DC/DC converter designed for powering power amplifiers in mobile phones, alongside dual low-noise low-dropout regulators for the radio frequency section. The device operates within an input voltage range of 2.7V to 5.5V and features a 17-MLF package measuring 2.5x2.8mm. It supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-performance DC/DC converter specifically intended for powering power amplifiers in mobile communication devices.
• Includes dual low-noise low-dropout regulators dedicated to supporting the remaining radio frequency sections.
• Utilizes a compact 17-MLF surface mount package suitable for space-constrained mobile applications.

Applications

• Powering power amplifiers in mobile phones
• Supplying dual low-noise regulators for radio frequency sections

Procurement Notes

Verify the manufacturer designation carefully, as the component was originally produced by Micrel before acquisition by Microchip Technology. Confirm that the specific suffix matches the required package and thermal specifications. Ensure compatibility with RoHS3 standards and check for any product change notifications regarding assembly sites or labeling updates prior to finalizing procurement orders.

Selection Notes

Select this component when designing mobile phone power architectures requiring integrated RF PA supply and low-noise regulation. Evaluate the trade-off between the integrated DC/DC converter efficiency and the noise performance of the dual LDOs. Consider the 17-MLF footprint constraints and ensure the design accommodates the specified operating temperature range for reliable mobile device operation.

Part Context

This part belongs to the MIC280 series of specialized power management ICs developed for mobile communications. Originally released under the Micrel brand, it is now cataloged under Microchip Technology following corporate acquisition. The series focuses on consolidating multiple power stages into single packages to reduce board space and improve system reliability in handheld devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other MIC280 series variants only if official datasheets confirm identical pinouts and electrical characteristics.
