MIC2807-NNYML-TR

Overview

The MIC2807-NNYML-TR is a digital power management IC from the MIC280 series, designed for mobile phone applications. It integrates a high-performance DC/DC converter intended for powering a power amplifier (PA) with 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 provides two output channels, both set at 2.85 V. The first channel delivers an output current of 30 mA at 2.85 V, while the second channel supports up to 200 mA at 2.85 V. The component utilizes a Buck topology and is housed in a 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 dedicated to supporting the remaining radio frequency circuitry.
• Features digital power management capabilities for efficient energy conversion and regulation.

Applications

• Powering power amplifiers in mobile phones
• Supplying power to radio frequency sections in wireless devices

Procurement Notes

Verify the specific suffix NNYML against official Microchip documentation to confirm pinout and electrical characteristics. Ensure compatibility with the target RF PA requirements. Confirm RoHS compliance status through the manufacturer's environmental declarations. Validate that the 17-MLF package dimensions match the PCB footprint design. Check for any recent product change notices affecting assembly or sourcing sites.

Selection Notes

Select this component when designing power systems for mobile handsets requiring integrated PA and RF supply rails. The dual LDO outputs provide clean power for sensitive RF stages. The Buck converter handles higher current demands for the PA efficiently. Consider the 2.7 V to 5.5 V input range for battery-powered operation. Verify thermal performance within the 17-MLF package for the intended load conditions.
