MIC2810-4LSYML

Overview

The MIC2810-4LSYML is a power management integrated circuit manufactured by Microchip Technology, formerly Micrel. It integrates three output channels configured as one buck converter and two low-dropout (LDO) regulators within a single package. The device operates with an input voltage range of 1.65V to 5.5V and supports switching frequencies up to 2MHz. It is housed in a 16-lead MLF® (4x4mm) surface-mount package. The component is rated for operation across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrates a high-efficiency synchronous buck converter alongside two independent LDO regulators for combined switching and linear regulation capabilities.
• Features a compact 16-lead MLF® package designed to minimize printed circuit board area requirements.
• Supports wide input voltage ranges suitable for various single-supply applications.

Applications

• Portable electronic devices requiring mixed regulation topologies
• Battery-powered systems utilizing both switching and linear regulation stages
• Embedded control boards with space-constrained power delivery needs

Procurement Notes

Verify the specific suffix '4LSYML' against official Microchip documentation to confirm pinout and electrical characteristics, as variations exist within the MIC2810 family. Ensure compatibility with the intended PCB footprint and thermal management strategy for the 16-MLF package. Confirm RoHS compliance status through current datasheets prior to procurement.

Selection Notes

Select this component when a design requires a single solution for both efficient step-down conversion and precise low-noise linear regulation. Consider the 2MHz switching frequency for smaller external passive components. Evaluate the thermal performance of the MLF package relative to the expected load currents on the buck and LDO outputs.

Part Context

The MIC2810 series represents a family of triple-output PMICs combining switching and linear technologies. Originally developed by Micrel, the product line was acquired by Microchip Technology. This specific variant targets applications needing multiple regulated rails from a single source while maintaining a small form factor.

Replacement Considerations

Direct substitutes include other MIC2810 variants with compatible pinouts such as MIC2810-4GSYML or MIC2810-4MSYML, provided the electrical parameters match the design requirements. Verify functional equivalence regarding enable logic and output configurations before substitution.
