MIC2225-4SYMT-TR

Overview

The MIC2225-4SYMT-TR is a dual-output voltage regulator from Microchip Technology, integrating a high-efficiency 2MHz PWM synchronous buck converter and a 300mA Low Dropout (LDO) regulator. The switching section accepts an input voltage range of 2.7V to 5.5V and delivers up to 600mA output current with internal power MOSFETs. It operates in a fixed 2MHz frequency mode in PWM operation. The device is housed in a compact 10-pin 2mm x 2mm Thin MLF package, designed for portable applications requiring core and I/O supply rails.

Feature Summary

• Integrates a high-efficiency 2MHz synchronous buck regulator with a 300mA LDO in a single ultra-small package
• Features fully integrated internal power MOSFET switches for simplified design and high efficiency exceeding 95%
• Includes micropower shutdown capability reducing current consumption to 1mA, along with thermal shutdown and current limit protection

Applications

• Application processors requiring separate core and I/O supply rails
• Camera DSPs needing low noise and small form factor power solutions
• Multimedia chipsets utilizing portable power architectures

Procurement Notes

Verify the specific suffix '4S' against official Microchip documentation to confirm fixed output voltage configuration, as suffixes often denote specific voltage options or temperature grades. Confirm package type is 10-pin Thin MLF. Check RoHS compliance status via the manufacturer's datasheet. Ensure ordering quantities align with reel specifications if applicable.

Selection Notes

Select this component when designing portable systems that require both a high-current switching rail and a low-noise linear rail from a single input source. The 2MHz switching frequency allows for smaller external inductors and capacitors compared to lower frequency alternatives. Ensure the application input voltage stays within the 2.7V to 5.5V range and that thermal management supports the 10-pin MLF package constraints.

Part Context

This part belongs to the MIC2225 family of dual-channel regulators. Similar parts in the series include MIC2225-GMYMT TR and MIC2225-G4YMT TR, which share the same functional architecture but may differ in output voltage configurations or packaging variants. The family is designed for space-constrained mobile electronics.

Replacement Considerations
