MIC2800-D24MYML

Overview

The MIC2800-D24MYML is a digital power management IC from Microchip Technology, formerly Micrel. It integrates a 2MHz DC/DC buck converter with two standalone Low Dropout (LDO) regulators in a single package. The device operates within an input voltage range of 2.7V to 5.5V and provides three distinct output voltages: 1.8V at 600mA, 1.2V at 300mA, and 2.8V at 300mA. It features LOWQ mode for ultra-low quiescent current and integrated power-on reset functionality.

Feature Summary

• Integrates a high-efficiency 2MHz PWM DC/DC converter with dual independent LDOs for flexible power distribution
• Features LOWQ mode operation that reduces total quiescent current to less than 30µA while maintaining low output noise
• Includes an integrated power-on reset circuit with adjustable delay time for reliable system startup sequencing

Applications

• Mobile phones
• GPS receivers
• Portable media players

Procurement Notes

Verify the manufacturer designation carefully, as the part was originally produced by Micrel before its acquisition by Microchip Technology. Confirm the specific suffix codes match the required output voltage configuration and packaging type. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications regarding assembly sites or labeling updates.

Selection Notes

Select this component when a compact solution is needed to generate multiple stable voltage rails from a single 2.7V to 5.5V source. The integration of a switching regulator with post-regulating LDOs allows for efficient bulk power conversion followed by clean, low-noise regulation for sensitive analog or RF circuits. Consider the thermal performance of the 16-pin QFN package under maximum load conditions.

Part Context

This component belongs to the MIC2800 series of digital power management ICs designed for portable electronics. The series combines switching and linear regulation technologies to optimize efficiency and board space. The specific model utilizes a 16-pin VFQFN package measuring 3mm x 3mm, suitable for surface-mount applications requiring high power density.
