MIC2206-1.2YML-TR

Overview

The MIC2206-1.2YML-TR is a dual-output power management IC from Microchip Technology, integrating one synchronous step-down (buck) converter and one low-dropout linear regulator (LDO). The buck channel operates at a fixed 2MHz switching frequency and delivers up to 600mA output current with an input voltage range of 2.7V to 5.5V. The LDO provides a fixed 1.2V output. Designed for mobile applications, it supports mode-voltage scaling to optimize efficiency across varying load conditions.

Feature Summary

• Integrates a high-efficiency synchronous buck converter and a precision LDO in a single compact package
• Features a fixed 2MHz switching frequency for the buck regulator to minimize external component size
• Supports mode-voltage scaling technology to enhance system efficiency during light-load operations
• Operates reliably within an extended industrial temperature range of -40°C to +125°C

Applications

• Mobile phone baseband processors requiring multiple regulated voltage rails
• Portable consumer electronics with strict space constraints
• Battery-powered devices utilizing mode-voltage scaling for extended runtime
• Embedded systems needing combined switching and linear regulation capabilities

Procurement Notes

Verify the specific suffix 'YML' corresponds to the 10-MLF (3x3) package and the '-TR' indicates tape-and-reel packaging. Confirm the '1.2' designation aligns with the required LDO output voltage. Ensure the source document explicitly lists this part number as active status from Microchip Technology to avoid obsolete components.

Selection Notes

Select this component when a design requires both a high-current switching regulator and a low-noise linear supply in a minimal footprint. It is suitable for applications where input voltages vary between 2.7V and 5.5V. The fixed 2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 600mA buck current rating meets the peak load requirements of the target circuit.

Part Context

This device belongs to Microchip's MIC2206 family of dual-output PMICs. It is designed to replace discrete solutions by combining buck and LDO functions. The part is commonly used in portable electronics where board space is limited. It shares functional similarities with other Micrel/Microchip dual-regulator ICs but offers specific integration benefits for mobile platforms.

Replacement Considerations

Check for direct pin-compatible substitutes such as the ADP2140 series if available, though electrical characteristics may differ. Verify that any replacement maintains the 2MHz switching frequency and compatible output current ratings. Ensure the alternative package matches the 10-MLF form factor for mechanical compatibility.
