MIC2205BML TR Equivalent & Substitute Parts

Part Overview

The MIC2205BML TR is a buck switching regulator IC from Microchip Technology designed for positive adjustable output applications. It delivers 600mA output current with an adjustable voltage range from 1V to 5.5V, operating from a 2.7V to 5.5V input supply. The device features a 2MHz switching frequency and integrated synchronous rectifier, housed in a 10-VFDFN Exposed Pad package (10-MLF®).

The MIC2205BML TR is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this regulator topology.

Parameter Comparison

Engineering Selection Recommendations

The MIC2205YML-TR is a direct substitute for the MIC2205BML TR. Both devices are manufactured by Microchip Technology and share identical electrical specifications and package configurations.

The primary distinction between these parts is product status and regulatory compliance. The MIC2205BML TR is obsolete, while the MIC2205YML-TR maintains active product status. Additionally, the MIC2205YML-TR is ROHS3 compliant, whereas the MIC2205BML TR is RoHS non-compliant. For new designs or ongoing production requiring regulatory compliance with modern environmental standards, the MIC2205YML-TR is the appropriate selection.

Both devices maintain identical moisture sensitivity levels (MSL 1, Unlimited) and are unaffected by REACH regulations, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the MIC2205YML-TR directly replace the MIC2205BML TR in existing designs?
