MIC2225-GMYMT-TR

Overview

The MIC2225-GMYMT-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 at a constant 2MHz frequency in PWM mode, achieving over 95% efficiency. The device is housed in a 10-pin 2mm x 2mm Thin MLF package and supports junction temperatures from -40°C to +125°C.

Feature Summary

• Integrates a 2MHz synchronous buck regulator and a 300mA LDO in a single ultra-small package
• Features fully integrated internal power MOSFET switches for high efficiency and compact design
• Includes micropower shutdown capability reducing current consumption to 1mA
• Provides thermal shutdown and current limit protection for system reliability

Applications

• Application processor core and I/O supply rails
• Camera DSP power management
• Multimedia chipset power distribution

Procurement Notes

Verify the specific suffix 'GMYMT' against the official Microchip datasheet to confirm pinout, output voltage options, and package dimensions. Ensure the ordering part number matches the required fixed output voltage variant if applicable. Confirm RoHS compliance status and manufacturing origin details directly with the supplier or manufacturer documentation prior to procurement.

Selection Notes

Select this component when space-constrained portable designs require simultaneous generation of a high-current digital rail and a low-noise analog rail. The 2MHz switching frequency allows for smaller external passive components compared to lower-frequency regulators. Verify that the load requirements do not exceed the 600mA buck or 300mA LDO limits simultaneously under worst-case thermal conditions.

Part Context

This part belongs to the MIC2225 family of dual-channel regulators designed for portable electronics. It replaces discrete solutions by combining DC/DC and LDO functions. Similar variants exist with different output voltages or packaging options within the same series, sharing the same core topology and control logic but differing in fixed output settings or thermal characteristics.

Replacement Considerations
