MIC2224YML

Overview

The MIC2224YML is a synchronous buck regulator from the Microchip MIC2224 series, designed for portable power applications. It operates with an input voltage range of 2.7 V to 5.5 V and provides an adjustable output voltage. The device features internal power MOSFETs capable of supplying up to 600 mA of output current. It utilizes a fixed 2 MHz PWM switching frequency to enable the use of small external components. The regulator is housed in a compact 10-pin 2 mm x 2 mm Thin MLF package.

Feature Summary

• Integrates high-efficiency synchronous buck converter with internal power MOSFETs
• Supports adjustable output voltage within specified operating ranges
• Operates at a constant 2 MHz switching frequency for compact design
• Includes protection mechanisms such as thermal shutdown and current limit

Applications

• Portable electronic devices requiring efficient step-down regulation
• Power supply rails for application processors
• Camera DSP power management
• Multimedia chipset core and I/O supplies

Procurement Notes

Verify the specific suffix and revision level against the official datasheet to ensure compatibility with your design requirements. Confirm availability status through authorized distributors, as lead times may vary. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference pinouts and thermal pad connections before finalizing the PCB layout.

Selection Notes

Select this component when a compact solution with 600 mA output capability is required. The 2 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Ensure the input voltage stays within the 2.7 V to 5.5 V range. Consider the thermal performance of the 2x2 mm MLF package under maximum load conditions.

Part Context

This part belongs to the MIC2224 family of ultra-small, high-efficiency DC/DC converters. It is positioned as a solution for space-constrained portable applications where low noise and high efficiency are critical. The family typically includes variants with different output configurations or packaging options to suit diverse system requirements.

Replacement Considerations

Check for direct substitutes within the MIC2224 series or compatible Micrel/Microchip buck regulators with similar current ratings and package dimensions. Verify electrical parameters such as switching frequency and input voltage range match the original design specifications.
