Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix 'SUR' to ensure correct reel packaging configuration. Confirm that the SON-16 package type matches the target PCB footprint requirements. Check moisture sensitivity level handling procedures if storage conditions exceed specified limits. Ensure compatibility with the intended switching frequency settings during initial circuit design validation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Choose this component when a wide input voltage range up to 36 V is required alongside moderate output current capabilities. Consider the LM43602DSUR for designs prioritizing efficiency through synchronous rectification without complex external control loops. Evaluate the trade-off between switching frequency selection and passive component sizing. Compare against lower-current alternatives if the 2 A limit exceeds actual application demands.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM43602 series of synchronous buck converters. It shares functional similarities with other members like the LM43602AQPWPTQ1 but differs in package type and automotive qualification status. The DSUR variant specifically denotes the SON-16 surface-mount package configuration. It serves as a non-automotive grade solution compared to Q1-rated counterparts in the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM43602DSUT for tape-and-reel variations. For automotive applications, consider LM43602AQPWPTQ1 despite package differences. Higher current variants may require checking thermal performance under identical load conditions.
