Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'VY+' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and temperature grade. Ensure the ordering part number matches the exact pinout and thermal pad requirements for your PCB layout design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages remain between 2.7V and 5.5V and output currents up to 3A are required. Consider the 2.2MHz frequency for minimizing inductor size compared to lower-frequency alternatives. Evaluate thermal performance based on ambient conditions and PCB copper area availability.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX204xx family of synchronous buck converters designed for space-constrained applications. It shares architectural similarities with other members but offers specific electrical characteristics tailored for low-voltage, medium-current scenarios common in modern portable hardware designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official cross-reference lists for direct replacements. Verify that any substitute maintains compatible input voltage ranges, current capabilities, and pin configurations to ensure seamless integration without redesigning the surrounding circuitry.
