MIC2810-CGJYML

Overview

The MIC2810-CGJYML is a digital power management IC featuring a 2 MHz DC/DC converter and two low VIN LDOs. It provides three fixed output voltages: 1.25 V, 1.4 V, and 2.5 V. Output currents are 600 mA for the DC/DC and 300 mA for each LDO. Input voltage ranges from 2.7 V to 5.5 V. Quiescent current is 200 nA. Line regulation is 0.2 %/V and load regulation is 0.1 %. PSRR is typically 45 dB. Operating temperature spans -40°C to +125°C. The device is housed in a 16-MLF package.

Feature Summary

• Integrates a high-frequency 2 MHz DC/DC buck converter with dual low VIN linear regulators for compact power solutions.
• Provides independent enable control for each of the three output channels to manage power sequencing and consumption.
• Features low quiescent current operation to enhance efficiency in battery-powered applications.

Applications

• Portable electronic devices requiring multiple regulated voltage rails
• Embedded systems with strict space constraints
• RF/EMI shielding applications

Procurement Notes

Verify the specific suffix (CGJYML) against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the component meets RoHS standards if required by your assembly process. Confirm that the 16-MLF package dimensions align with your PCB footprint design. Check for moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component when a single IC solution is needed to replace multiple discrete regulators. It is suitable for designs requiring a 2 MHz switching frequency to minimize passive component size. Consider the 600 mA DC/DC output for primary loads and the 300 mA LDOs for sensitive analog circuits. Verify input voltage stability within the 2.7 V to 5.5 V range.

Part Context

This part belongs to the MIC2810 family of digital power management ICs manufactured by Microchip Technology, which acquired Micrel. The family includes variants with different output configurations and package options. The MIC2810 series is designed to simplify power architecture in portable electronics by integrating switching and linear regulation on a single die.

Replacement Considerations

Check for MIC2810-1J6JYML-TR or MIC2810-4LSYML-TR as potential functional equivalents. Verify that substitute parts match the 16-MLF package and output specifications. Confirm pin-to-pin compatibility before replacement.
