MCP1624T-I/MC

Overview

The MCP1624T-I/MC is a synchronous boost DC-DC converter designed for low-voltage input applications. It operates with an input voltage range of 0.35V to 5.5V and provides a regulated output between 2V and 5.5V. The device delivers up to 150mA of output current at a fixed switching frequency of 500kHz. It features an integrated output disconnect switch and supports both PWM and PFM modes. The component is housed in an 8-VFDFN exposed pad package and is qualified under AEC-Q100 standards for automotive reliability.

Feature Summary

• Synchronous step-up topology for high efficiency
• Integrated output disconnect switch
• Supports PWM and PFM operation modes

Applications

• PIC microcontroller power supply systems
• Low-voltage battery-powered devices
• Automotive electronic modules

Procurement Notes

Verify the specific suffix 'I/MC' against the manufacturer's official datasheet to confirm the exact temperature grade and packaging configuration. Ensure that the AEC-Q100 qualification status aligns with your design requirements. Cross-reference the pinout and thermal pad specifications with the provided CAD models before finalizing the PCB layout.

Selection Notes

Select this component when a compact, high-efficiency solution is required for boosting low input voltages. The synchronous design offers superior performance compared to asynchronous alternatives. Consider the 500kHz frequency for balancing component size and efficiency. Verify that the load current requirements do not exceed the 150mA limit under all operating conditions.
