MIC2206-9IYML-TR

Overview

The MIC2206-9IYML-TR is a dual-output DC-DC switching voltage regulator IC manufactured by Microchip Technology. It integrates a synchronous step-down (buck) converter and a low-dropout linear regulator (LDO) within a single package. The device features a fixed 2MHz switching frequency for the buck section, supporting an input voltage range of 2.7V to 5.5V. The LDO output provides a fixed 3.3V supply. Designed for space-constrained applications, it utilizes a compact 10-MLF® (3x3mm) surface-mount package with exposed pad thermal enhancement.

Feature Summary

• Integrates a synchronous buck converter and a fixed-voltage LDO in a single component
• Operates at a fixed 2MHz switching frequency to minimize external passive size
• Features a compact 10-pin MLF package with exposed pad for efficient thermal dissipation

Applications

• Voltage scaling for processors and FPGAs requiring multiple rails
• Portable consumer electronics with strict space limitations
• Industrial control systems needing combined switching and linear regulation

Procurement Notes

Verify the specific suffix '9' indicates the fixed 3.3V LDO output configuration. Confirm the 'I' designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure the 'TR' suffix matches the required tape-and-reel packaging quantity. Cross-reference the manufacturer part number against the latest datasheet revision to confirm pinout compatibility.

Selection Notes

Select this component when a design requires both a programmable buck output and a fixed auxiliary rail from a single IC footprint. It is suitable for inputs between 2.7V and 5.5V where board space is critical. Consider the 2MHz frequency for smaller inductor selection compared to lower-frequency alternatives. Evaluate thermal performance requirements given the small 3x3mm package dimensions.

Part Context

This part belongs to the MIC2206 family of mixed-signal power management devices. It combines the efficiency of synchronous switching with the low noise of an LDO. The family is designed for applications requiring high integration and minimal bill-of-materials count. It serves as a solution for multi-rail power distribution in compact electronic systems.

Replacement Considerations

Direct substitutes include other Micrel/Microchip dual-output regulators such as the MIC2205 or MIC2207 series, provided pinouts and electrical specifications align. Verify that alternative parts support the same 2MHz frequency and input voltage range. Check package compatibility for the 10-MLF form factor.
