LM2590HVT-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2590HVT-ADJ/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a 150-kHz, 1-A step-down voltage regulator. It operates with an input voltage range of 4.5 V to 60 V and provides an adjustable output voltage between 1.2 V and 57 V. The device ensures a guaranteed 1-A output load current with ±4% maximum tolerance over line and load conditions. Packaged in a TO-220-7 form lead configuration, it supports surface mount installation and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic switching regulator designed for high-efficiency step-down conversion
• Fixed 150-kHz internal oscillator eliminates external timing component requirements
• Built-in thermal shutdown and current limit protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

• Efficient buck converters for battery-powered systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates the TO-220-7 package variant distinct from other pinouts. Confirm 'NOPB' denotes lead-free and RoHS compliance status. Cross-reference the manufacturer datasheet to ensure the adjustable output version matches circuit design requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust 1-A buck converter is required with a wide input voltage range up to 60 V. The TO-220-7 package facilitates heat dissipation for higher power applications compared to smaller surface-mount options. Ensure the application demands an adjustable output voltage rather than fixed voltage variants within the LM2590HV family.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2590HV series of SIMPLE SWITCHER power converters. It shares functional similarities with the LM2596 and LM2594 families but offers a higher input voltage capability. The 'HVT' designation specifically identifies the high-voltage adjustable version in the TO-220-7 package format.
