MIC2800-G1JJYML-TR

Overview

The MIC2800-G1JJYML-TR is a digital power management IC from Microchip Technology, housed in a 16-pin QFN package. It integrates one buck converter and two linear regulators, operating within an input voltage range of 2.7V to 5.5V. The switching frequency is fixed at 2MHz. Output 1 provides 1.8V at 600mA, while Outputs 2 and 3 deliver 1.2V at 300mA each. The device supports surface mount installation and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a single DC-DC buck converter with two low-dropout linear regulators for multi-rail power distribution.
• Features LowQ Mode operation to minimize quiescent current during standby or light-load conditions.
• Includes a Power-On Reset (POR) circuit to ensure system stability during power-up sequences.
• Utilizes digital control architecture for precise regulation and efficient power management.

Applications

• Portable consumer electronics requiring compact multi-voltage power solutions
• Embedded systems needing integrated buck and LDO regulation
• Industrial applications with wide temperature operational requirements

Procurement Notes

Verify the specific suffix G1JJYML against the official Microchip datasheet to confirm output voltages and current ratings match design requirements. Ensure compatibility with RoHS3 standards and check moisture sensitivity level (MSL 3) handling procedures during assembly. Confirm lead times and availability through authorized distributors as supply chain conditions may vary.

Selection Notes

Select this component when a single IC solution is needed to generate three distinct voltage rails from a 2.7V to 5.5V source. It is suitable for designs prioritizing board space reduction by combining switching and linear regulation. Consider the 2MHz switching frequency for EMI management and the fixed output voltages for compatibility with target loads.
