Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix E7001842 against official Texas Instruments documentation to confirm it denotes a standard commercial grade device or a specific tape-and-reel configuration. Ensure the ordering part number matches the exact package type and temperature rating required for your design. Cross-reference with the manufacturer's latest datasheet to validate availability and compliance status before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters requiring high input voltages up to 60 V and output currents near 2 A. The adjustable output variant provides flexibility for custom voltage rails. Consider the TO-263 package for its thermal performance in surface-mount applications. Ensure adequate heatsinking or PCB copper area is allocated to manage power dissipation at maximum load conditions within the specified temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2592HV family of SIMPLE SWITCHER power converters. It shares core architecture with other variants like the LM2592HVS but differs in package style and output configuration. The 'HV' designation indicates high-voltage input capability, distinguishing it from standard low-voltage switching regulators. It is designed for robust performance in industrial and automotive environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible substitutes include the LM2592HVS-ADJ/NOPB and LM2592HVSX-ADJ/NOPB. Verify that replacement parts maintain identical electrical characteristics, particularly the 60 V maximum input rating and 2 A current capacity. Confirm package dimensions match the TO-263 footprint to ensure mechanical compatibility.
