MIC2800-G4JYML

Overview

The MIC2800-G4JYML is a digital power management IC from the MIC2800 series, manufactured by Microchip Technology. It integrates one DC-DC buck converter and two linear regulators within a single QFN-16 package. The device operates with an input voltage range of 2.7 V to 5.5 V and supports output voltages between 1.2 V and 2.5 V. It features a switching frequency of 2 MHz and includes LowQ Mode for efficiency optimization alongside Power-On Reset (POR) functionality. The component is rated for operation between -40°C and +125°C.

Feature Summary

• Integrates a synchronous buck converter and two low-dropout linear regulators in a compact surface-mount package.
• Features LowQ Mode technology to optimize power consumption during light-load conditions.
• Includes integrated Power-On Reset (POR) circuitry for reliable system initialization.

Applications

• Portable electronic devices requiring efficient multi-rail power distribution
• Embedded systems utilizing microcontrollers or digital signal processors
• Battery-powered equipment needing extended operational life through optimized power modes

Procurement Notes

Verify the manufacturer designation carefully, as the part originates from Micrel, which was acquired by Microchip Technology. Ensure the specific suffix matches the required output configuration and packaging type. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications before finalizing procurement orders.

Selection Notes

Select this component when a combined solution for switching regulation and linear noise-sensitive supplies is required. The 2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance of the QFN-16 package relative to your board layout and ambient operating temperature constraints.

Part Context

This part belongs to the MIC2800 family of digital power management ICs designed for space-constrained applications. The series offers various output configurations to suit different system architectures. The G4 suffix typically indicates lead-free and RoHS-compliant manufacturing standards consistent with modern environmental regulations.

Replacement Considerations

Check for other MIC2800 variants with different output voltage settings if the current configuration does not match system requirements. Verify pin-to-pin compatibility with existing designs when considering alternative suppliers or updated revisions from the manufacturer.
