Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official documentation, as variations such as +T (tape and reel) or standard tube packaging may exist within the MAX5035D family. Confirm that the requested part number matches the exact temperature grade and package style required for your design. Cross-reference the manufacturer's latest datasheet to ensure the component remains active and suitable for new designs, as availability status can change.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters that require wide input voltage ranges exceeding standard 40 V regulators. Ensure the thermal performance of the SOIC-8 package meets the application's heat dissipation requirements at full load. Verify that the 125 kHz frequency aligns with EMI constraints and inductor selection criteria for the target system.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX5035 series of high-efficiency MAXPower step-down regulators. The series offers various fixed and adjustable output options in compact packages.
