Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix matches the required RoHS compliance status and tape-and-reel packaging configuration. Confirm the pinout compatibility if replacing legacy inventory with current TI production runs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a wide input voltage range up to 60 V with moderate current demands. The fixed 150 kHz frequency allows for smaller passive components compared to lower-frequency regulators. Ensure the inductor selection aligns with the specified ripple current requirements for stable operation across the full load range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2590HV series of high-voltage step-down converters. It shares architectural similarities with the LM2576HV but offers higher switching frequencies and adjusted current capabilities. The family is designed for simplified design processes using standard off-the-shelf components.
