MIC2206-83YML-TR

Overview

The MIC2206-83YML-TR is a high-efficiency, 2MHz PWM synchronous buck regulator with an integrated LowQ® LDO standby mode. It operates within an input voltage range of 2.7V to 5.5V and delivers up to 1A output current. The device features ultra-low quiescent current consumption of 18µA in standby mode, supporting rapid voltage scaling applications. It includes comprehensive protection mechanisms such as over-current, thermal shutdown, and soft-start functionality.

Feature Summary

• Integrates a synchronous buck converter with a dedicated LowQ® LDO for ultra-low power standby operation
• Supports programmable switching frequency up to 2MHz for optimized component size and transient response
• Features built-in protection against over-current conditions, thermal overload, and controlled soft-start sequencing

Applications

• Portable consumer electronics requiring low standby power consumption
• Voltage scaling interfaces for microprocessors and FPGAs
• Battery-powered devices needing efficient step-down regulation

Procurement Notes

Verify the specific suffix '83' corresponds to the required output voltage configuration or enable pin logic before procurement. Confirm package availability matches the 10-MLF® (3x3mm) requirement. Ensure compatibility with RoHS and REACH standards as per Microchip's current manufacturing declarations. Cross-reference datasheet revision dates to validate feature sets.

Selection Notes

Select this component when system design demands minimal quiescent current during idle states alongside efficient active regulation. The integrated LDO simplifies biasing requirements for control circuits. Evaluate thermal performance under maximum load conditions given the compact MLF package. Ensure input voltage stability remains within the 2.7V to 5.5V operational window for reliable regulation.

Part Context

This part belongs to the MIC2206 family of mixed-signal PMICs designed for portable applications. It combines switching regulation with linear standby modes to maximize battery life. The MLF package provides a small footprint suitable for space-constrained mobile devices. It serves as a power management solution for systems requiring both high efficiency and deep sleep capabilities.

Replacement Considerations

Check for direct substitutes within the MIC2206 series with different suffixes for varying enable thresholds. Verify pin-to-pin compatibility with alternative regulators from other manufacturers if supply constraints exist. Ensure switching frequency and output current ratings meet or exceed original design specifications.
