MIC2225-4OYMT-TR

Overview

The MIC2225-4OYMT-TR is a dual-output voltage regulator manufactured by Microchip Technology, formerly Micrel. It integrates a high-efficiency 2MHz PWM synchronous buck converter and a 300mA Low Dropout (LDO) regulator within a single ultra-small package. The DC-DC section accepts an input voltage range of 2.7V to 5.5V and delivers up to 600mA output current with greater than 95% efficiency. The LDO provides stable auxiliary power rails. The device operates in a 10-pin Thin MLF package rated for junction temperatures from -40°C to +125°C.

Feature Summary

• Integrates a 2MHz synchronous buck converter and a 300mA LDO in one compact solution
• Delivers high efficiency exceeding 95% with internal power MOSFETs
• Features ultra-low noise characteristics suitable for sensitive analog circuits
• Includes comprehensive protection mechanisms such as thermal shutdown and current limit

Applications

• Power supply rails for application processors
• Core and I/O supplies for camera DSPs
• Power management for multimedia chipsets

Procurement Notes

Verify the specific suffix '4O' against official Microchip documentation to confirm the fixed output voltage configuration. Ensure the ordering part number matches the required tape-and-reel packaging quantity. Confirm RoHS compliance status and lead-free specifications prior to procurement to meet environmental standards.

Selection Notes

Select this component when space-constrained designs require both a high-current switching regulator and a low-noise linear regulator. The integrated topology reduces external component count compared to discrete solutions. Consider the 2MHz switching frequency for smaller passive components while evaluating electromagnetic interference requirements for the target application environment.

Part Context

This part belongs to the MIC2225 family of dual-channel regulators designed for portable electronics. The series combines switching and linear regulation technologies to address complex power distribution needs in mobile devices. The manufacturer transitioned from Micrel to Microchip Technology, maintaining the same functional specifications and pinout compatibility across the product line.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with other MIC2225 variants only if the output voltage settings and package dimensions match exactly.
