Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'HV' indicates the high-voltage variant rated for 75V switch voltage, distinct from standard versions. Confirm the 'CT' suffix corresponds to the TO-220-5 through-hole package. Ensure RoHS compliance matches project requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm pinout and electrical specifications before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits requiring a 2.5A switch current capability with an input voltage up to 60V. The 40kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the TO-220-5 package for applications requiring robust thermal dissipation via through-hole mounting. Verify that the required topology aligns with the device's support for buck, boost, and other standard configurations.
