MIC2800-D2FMYML-TR

Overview

The MIC2800-D2FMYML-TR is a digital power management IC from Microchip Technology, housed in a 16-pin QFN package. It integrates a 2 MHz, 600 mA DC/DC converter and dual 300 mA linear regulators. The device operates within an input voltage range of 2.7 V to 5.5 V and supports output voltages from 800 mV to 3.6 V. It features LowQ Mode for efficiency optimization and includes Power-On Reset (POR) functionality. The component is rated for operation between -40°C and +125°C.

Feature Summary

• Integrates a high-frequency switching regulator with two low-dropout linear regulators for multi-rail power generation.
• Includes LowQ Mode technology to enhance system efficiency during light-load conditions.
• Provides integrated Power-On Reset (POR) circuitry to ensure reliable system initialization.

Applications

• Portable electronic devices requiring efficient multi-voltage power distribution
• Embedded systems utilizing digital power management architectures
• Industrial control modules operating in extended temperature environments

Procurement Notes

Verify the specific suffix D2FM against official Microchip documentation to confirm pinout and electrical characteristics. Ensure compatibility with your PCB footprint for the 16-pin QFN EP package. Confirm that the 2.7 V to 5.5 V input range aligns with your system's supply rails before integration.

Selection Notes

Select this component when a compact solution combining switching and linear regulation is required. The 2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the combined load current requirements for the three outputs do not exceed the specified limits of 600 mA and 300 mA per LDO.

Part Context

This part belongs to the MIC2800 family of digital power management ICs designed by Microchip Technology. These devices are engineered to replace discrete power solutions, reducing board space and simplifying design complexity. The family typically offers configurable outputs and advanced monitoring capabilities for modern embedded applications.

Replacement Considerations

Consult Microchip datasheet DS20005839 for direct substitutes. Verify pin-to-pin compatibility and thermal performance if replacing existing designs. Ensure the replacement maintains the same 16-pin QFN EP package dimensions.
