MIC2810-4LSYML-TR

Overview

The MIC2810-4LSYML-TR is a Power Management IC (PMIC) manufactured by Microchip Technology, housed in a 16-pin MLF package. It integrates one buck converter and two low-dropout (LDO) linear regulators to provide three independent output channels. The device operates with an input voltage range of 1.65V to 5.5V and supports switching frequencies up to 2MHz. Output specifications include a 600mA buck channel at 1.2V, and two LDO channels providing 300mA each at fixed voltages of 1.8V and 3.3V. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency synchronous buck converter alongside two precision LDO regulators for comprehensive power management.
• Features LowQ Mode technology designed to minimize quiescent current consumption during light-load or standby conditions.
• Includes a Power-On Reset (POR) circuit to ensure system stability by monitoring supply voltages and managing reset signals.

Applications

• Portable consumer electronics requiring multi-rail power sequencing
• Embedded systems utilizing mixed-signal processors
• Battery-powered devices needing efficient step-down regulation

Procurement Notes

Verify the specific suffix '4L' against the official datasheet to confirm the exact output voltage configurations and current ratings, as variations exist within the MIC2810 family. Ensure compatibility with the required thermal dissipation for the 16-MLF package under maximum load conditions. Confirm that the 1.65V minimum input voltage aligns with your battery or supply architecture.

Selection Notes

Select this component when a single IC solution is needed to replace multiple discrete regulators, thereby reducing board space. It is suitable for designs requiring a high-current buck rail for logic cores and lower-current LDO rails for sensitive analog circuits. Consider the 2MHz switching frequency for smaller external inductor sizes compared to lower-frequency alternatives.

Part Context
