MIC2827-B2YMT-TR

Overview

The MIC2827-B2YMT-TR is a programmable power management IC designed for processor applications. It integrates a single 500mA step-down switching regulator and two 150mA low-dropout (LDO) regulators. The device features I2C voltage control and sequencing capabilities, allowing precise configuration of output voltages. It operates within a supply voltage range of 2.7V to 5.5V and supports an operating temperature range from -40°C to 125°C. The component is housed in a 14-TMLF package with dimensions of 2.5x2.5mm.

Feature Summary

• Integrates one high-current buck converter and dual LDOs for efficient multi-rail power generation
• Enables digital control and sequencing via I2C interface for flexible system power-up sequences
• Supports programmable output voltages to meet specific processor core and peripheral requirements

Applications

• Processor power management systems
• Embedded computing platforms requiring sequenced power rails
• Portable devices utilizing I2C-configurable power supplies

Procurement Notes

Verify the current lifecycle status as this part may be discontinued or subject to last-time buy notices. Confirm that the 14-TMLF footprint matches your PCB design constraints. Ensure I2C address configurations align with your system bus topology. Check for updated RoHS compliance documentation before finalizing procurement plans.

Selection Notes

Select this component when a compact solution combining switching efficiency and LDO precision is required for processor cores. The integrated I2C control allows dynamic voltage scaling without external resistors. Consider the thermal performance of the exposed pad TMLF package for high-current buck operation. Verify that the input voltage range covers your system's maximum supply levels.
