Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix 'EVVO' matches the manufacturer designation on official datasheets. Confirm the package type is TO-263-5L and the output configuration is adjustable. Ensure compliance with RoHS3 standards and check for any specific handling requirements related to the surface-mount topology.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an adjustable output voltage between 1.2V and 40V is required with up to 2A load capacity. The 150kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 57V maximum input rating for higher voltage bus applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM2575HVS-12-EV but differs by offering an adjustable output rather than a fixed voltage. The series is characterized by high efficiency and minimal external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include the LM2575HVS-ADJ from Texas Instruments or National Semiconductor. Verify pin compatibility and thermal performance when replacing with equivalent parts from other manufacturers.
