MIC2807-NNYML TR

Overview

The MIC2807-NNYML 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 power amplifiers (PA), alongside dual low-noise low dropout (LDO) regulators for the rest of the radio frequency (RF) section. The device operates with an input voltage range of 2.7 V to 5.5 V. The DC/DC converter provides an output voltage of 2.85 V at 30 mA, while the LDOs provide 2.85 V at 200 mA each.

Feature Summary

• Integrates a high-efficiency DC/DC buck converter optimized for RF power amplifier supply
• Includes dual low-noise low dropout linear regulators for sensitive RF circuitry
• Supports digital power management features including LowQ mode and Power-On Reset

Applications

• Powering power amplifiers in mobile phones
• Supplying radio frequency sections in wireless communication devices
• Mobile phone baseband and RF subsystem power management

Procurement Notes

Verify the specific suffix NNYML against official Microchip documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing board layouts and thermal requirements. Confirm RoHS compliance status through current datasheets. Validate that the reel packaging matches assembly line specifications. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing power systems for mobile handsets requiring dedicated PA supply and clean RF rails. Consider the integrated nature of the DC/DC and LDOs to reduce bill of materials count. Evaluate the 2.7 V to 5.5 V input range against the system battery profile. Assess the noise performance of the LDOs against RF sensitivity requirements. Verify package availability in 17-MLF format for PCB design constraints.

Part Context

The MIC2807 belongs to the MIC280 series of specialized PMICs developed by Microchip Technology, formerly Micrel. This family targets portable electronic devices, particularly smartphones, where space efficiency and power integrity are critical. The integration of switching and linear regulation in a single package helps minimize solution size and improve overall system efficiency compared to discrete solutions.

Replacement Considerations

Check for MIC2807 variants with different suffixes such as MM or NG which may offer similar functionality but distinct pinouts or electrical specs. Consult official substitution guides for cross-referencing with older Micrel part numbers. Ensure any replacement maintains the same 17-MLF package footprint and thermal dissipation characteristics.
