MIC2206-1.8BML TR

Overview

The MIC2206-1.8BML TR is a dual-output power management IC combining a synchronous step-down converter and an LDO regulator. It features a fixed 1.8V output at 1A for the buck converter and a fixed 1V output at 120mA for the LDO. The device operates with a switching frequency of 2MHz and is housed in a 10-MLF (3x3) package. This component is classified as obsolete and is no longer manufactured by Microchip Technology.

Feature Summary

• Integrates a synchronous buck converter and a linear low-dropout regulator in a single package
• Provides independent fixed voltage outputs for mixed-signal power requirements
• Utilizes a compact 10-lead micro lead frame package for space-constrained designs

Applications

• Portable electronic devices requiring efficient power conversion
• Mixed-signal systems needing isolated noise-sensitive power rails
• Battery-powered equipment utilizing synchronous step-down topology

Procurement Notes

Verify availability through authorized distributors or secondary markets, as this part is officially obsolete. Confirm exact suffix variations and RoHS compliance status, as legacy stock may differ from current environmental standards. Request original manufacturer documentation to validate authenticity before procurement.

Selection Notes

Select this component only if legacy design compatibility is required. Evaluate alternative active parts from the same family that offer updated manufacturing support. Ensure input voltage ranges and thermal performance meet system specifications given the fixed output configuration.

Part Context

This device belongs to the MIC2206 series of dual-output regulators designed for portable applications. It merges switching efficiency with LDO precision. The specific model indicates fixed output voltages and a MLF package. It serves as a complete power solution for systems requiring multiple regulated rails from a single source.

Replacement Considerations

Consult Microchip official substitution guides for active equivalents. Verify pin compatibility and electrical parameters when selecting substitutes. Ensure replacement components maintain the required output currents and switching frequencies.
