MCP1624-I/MC

Overview

The MCP1624-I/MC is a synchronous boost switching regulator manufactured by Microchip Technology, designed for low-power applications. It operates with an input voltage range of 800 mV to 5.5 V and provides an adjustable output voltage between 2 V and 5.5 V. The device delivers up to 50 mA of output current at a fixed switching frequency of 500 kHz. Key electrical characteristics include a maximum static current of 19 uA and operation within a temperature range of -40°C to +85°C. It is housed in an 8-lead DFN package.

Feature Summary

• Synchronous rectification architecture for enhanced power conversion efficiency
• Integrated power switch and control logic for simplified design
• Low quiescent current consumption suitable for battery-powered systems

Applications

• Portable electronic devices requiring efficient step-up voltage regulation
• Battery-operated sensor nodes and IoT modules
• Systems utilizing single-cell lithium-ion or alkaline batteries

Procurement Notes

Verify the specific suffix 'I/MC' against official Microchip documentation to confirm industrial temperature rating and DFN-8 packaging. Ensure compatibility with required output voltage settings and input source constraints before ordering. Cross-reference datasheet revisions to validate pinout and electrical specifications for the final design implementation.

Selection Notes

Select this component when a compact solution is needed for boosting low input voltages to stable levels. The synchronous topology offers better efficiency than asynchronous alternatives at moderate loads. Consider the 50 mA output limit and 500 kHz frequency when designing passive components. Verify that the 800 mV minimum input requirement aligns with the available power source under all operating conditions.

Part Context

This part belongs to the MCP162x family of synchronous boost converters from Microchip Technology. These regulators are engineered to provide reliable power management for microcontrollers and peripheral circuits. The series emphasizes high efficiency and low standby current to extend battery life in portable consumer electronics and industrial monitoring equipment.

Replacement Considerations

Consult official Microchip documentation for verified cross-reference part numbers. Direct replacements must match the synchronous boost topology, DFN-8 package, and electrical performance limits.
