MIC2810-44MYML

Overview

The MIC2810-44MYML is a digital power management IC from Microchip Technology, integrating a 2 MHz, 600 mA DC/DC converter with two 300 mA low VIN LDOs. It operates within an input voltage range of 2.7 V to 5.5 V and provides adjustable output voltages from 0.8 V to 3.6 V for the switching regulator. The device features LowQ mode for efficiency optimization and includes Power-On Reset (POR) functionality. It is housed in a compact QFN-16 (3x3 mm) package and supports an operating junction temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-frequency synchronous buck converter with dual low-dropout linear regulators for combined power management.
• Includes LowQ mode operation to enhance system efficiency during light-load conditions.
• Features built-in Power-On Reset (POR) circuitry to ensure reliable system initialization.

Applications

• Portable consumer electronics requiring efficient multi-rail power distribution
• Industrial control systems needing robust power management in compact form factors
• Embedded computing platforms utilizing mixed-signal power architectures

Procurement Notes

Verify the manufacturer designation carefully, as the component is manufactured by Microchip Technology despite historical associations with Micrel. Confirm the specific suffix '44MYML' matches the required output configurations and package type. Ensure compatibility with the intended input voltage range and thermal requirements before procurement.

Selection Notes

Select this component when a single-chip solution is needed for both switching regulation and linear regulation in space-constrained designs. Consider the 2 MHz switching frequency for smaller external passive components. Evaluate the need for LowQ mode if battery life or standby power consumption is critical to the application design.

Part Context

This part belongs to the MIC2810 family of digital power management ICs. It combines a step-down DC/DC converter with dual LDOs, offering a consolidated power solution. The family is designed for applications requiring multiple voltage rails from a single source, reducing board space and component count compared to discrete solutions.

Replacement Considerations

Consult official Microchip documentation for verified substitute part numbers within the MIC2810 series. Cross-referencing should be limited to officially documented equivalents to ensure functional and pin-out compatibility.
