MIC2807-OOYML-TR

Overview

The MIC2807-OOYML-TR is a specialized power management integrated circuit (PMIC) from Microchip Technology, designed for mobile phone applications. It integrates a high-performance DC/DC buck converter intended for powering a power amplifier (PA), alongside dual low-noise low dropout (LDO) regulators for the rest of the radio frequency (RF) section. The device operates within an input voltage range of 2.7 V to 5.5 V. It features a Buck topology for the main converter and provides specific output voltages, including 2.85 V outputs with defined current capabilities such as 30 mA and 200 mA at 2.85 V. The component is housed in a compact 17-MLF package.

Feature Summary

• Integrates a high-performance DC/DC converter specifically optimized for powering power amplifiers in mobile communication devices.
• Includes dual low-noise low dropout (LDO) regulators designed to supply clean power to sensitive radio frequency sections.
• Features digital power management capabilities with LowQ Mode for enhanced efficiency and Power-On Reset (POR) functionality.

Applications

• Powering power amplifiers (PA) in mobile phones
• Supplying power to radio frequency (RF) sections in wireless devices
• Mobile phone baseband power management systems

Procurement Notes

Verify the exact suffix 'OOYML' against official Microchip documentation, as standard listings often show variants like 'NNYML' or 'MMYML'. Confirm pinout compatibility and thermal requirements for the 17-MLF package before integration. Ensure the selected variant matches the required output voltage and current specifications for your specific PA and RF load designs. Check for RoHS compliance status in the latest datasheet revision.

Selection Notes

Select this component when designing power systems for mobile handsets requiring integrated PA and RF regulation. Consider the MIC2807 series if space constraints favor the 17-MLF package over larger QFN options. Evaluate the noise performance of the LDOs against the sensitivity of your RF front-end components. Compare input voltage ranges and output current capabilities with other MIC2800 series variants to ensure optimal system efficiency and thermal management.

Part Context

The MIC2807 belongs to the MIC280x family of digital power management ICs from Microchip Technology. This family targets portable electronics, particularly mobile phones, by combining switching regulators and LDOs in a single small footprint. The MIC2807 specifically focuses on the demanding power needs of modern RF architectures, integrating both high-current buck conversion and precision linear regulation to support complex power sequencing and efficiency requirements in cellular devices.

Replacement Considerations

Publicly confirmed substitute part numbers for MIC2807-OOYML-TR are not available in the provided source material. Verify cross-references with MIC2807-MMYML-TR or MIC2807-NNYML-TR only if official Microchip documentation confirms functional equivalence and pin compatibility.
