Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'QMRX' indicates tape-and-reel packaging distinct from tube variants. Confirm AEC-Q100 automotive qualification status matches project requirements. Ensure the adjustable output configuration aligns with external feedback resistor specifications. Validate thermal performance within the specified operating temperature range.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3 A output current capability is required alongside a wide input voltage range up to 42 V. The 500 kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. The SO-PowerPAD package provides efficient thermal dissipation for surface-mount applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22673 family of SIMPLE SWITCHER regulators. It shares core architecture with other variants like LM22673QMR but differs in packaging format. The family targets robust, high-efficiency step-down conversion for demanding environments.
