MIC2206-1.8YML-TR

Overview

The MIC2206-1.8YML-TR is a dual-output power management IC from Microchip Technology, integrating a 2MHz synchronous buck converter and a low-dropout (LDO) linear regulator in a single package. It provides a fixed 1.8V output from the switching regulator and an adjustable or secondary output from the LDO section. Designed for voltage scaling applications, it operates with an input voltage range of 2.7V to 5.5V. The device supports up to 3A output current for the buck converter and features a compact 10-MLF® (3x3 mm) surface-mount package suitable for space-constrained portable electronics.

Feature Summary

• Integrates a high-efficiency 2MHz synchronous step-down converter with a complementary linear regulator for combined power delivery.
• Supports dynamic voltage scaling sequences through integrated control logic for multi-rail system power-up and power-down.
• Features a compact 10-lead MLF package designed to minimize printed circuit board area requirements.

Applications

• Portable consumer electronics requiring efficient multi-voltage rail generation
• Mobile communication devices utilizing dynamic voltage scaling for power optimization
• Embedded systems needing simultaneous switching and linear regulation in a small footprint

Procurement Notes

Verify the specific suffix 'YML' confirms the 10-MLF package and thermal pad configuration required for your layout. Confirm that the fixed 1.8V output meets your primary rail requirement before procurement. Ensure compatibility with your system's sequencing needs, as this part integrates both switching and linear regulators. Check for any recent Product Change Notifications regarding manufacturing location or packaging updates from Microchip Technology.

Selection Notes

Select this component when a design requires both high-efficiency switching regulation and clean linear regulation within a limited board space. It is suitable for applications where the primary load demands higher current efficiency while secondary loads require low noise. Consider the 2MHz switching frequency for smaller external passive components compared to lower-frequency alternatives. Ensure the input voltage range of 2.7V to 5.5V aligns with your battery or supply characteristics.

Part Context

This part belongs to the MIC2206 family of dual-mode power management ICs. It combines Micrel/Microchip's synchronous buck technology with LDO capabilities. The MIC2206 series is designed for portable applications requiring multiple voltage rails from a single source. It differs from single-regulator parts by offering integrated sequencing and mixed-mode regulation in one compact solution.

Replacement Considerations

Direct replacements may include other MIC2206 variants with different output voltages or pin configurations. Verify pin-to-pin compatibility if substituting with similar dual-regulator ICs from other manufacturers. Ensure the replacement supports the same 2MHz switching frequency and thermal performance in the 10-MLF package.
