LM2590HVS-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2590HVS-ADJ/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, operating as a step-down switching regulator with a fixed 150 kHz frequency. It supports an input voltage range of 4.5 V to 60 V and delivers up to 1 A output current. The adjustable output voltage spans from 1.2 V to 57 V. Housed in a TO-263-7 (DDPAK) surface-mount package, it functions within a junction temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference manufacturer documentation for any recent design changes or lifecycle notices before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters requiring high input voltages up to 60 V with moderate current demands. It is suitable for applications prioritizing minimal external component count due to integrated control circuitry. Evaluate thermal performance requirements carefully given the single-output topology and package constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2590HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM2592HV but differs in maximum output current ratings. The series is designed for cost-effective, high-efficiency DC-DC conversion solutions using standard off-the-shelf passive components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2590HVSX-ADJ/NOPB. Verify pinout and thermal pad configurations when replacing across different package variants within the same family.
