LM2591HVT-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2591HVT-5.0/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, designed as a step-down voltage regulator. It operates at a fixed switching frequency of 150 kHz and delivers a regulated output current of 1 A. The device provides a fixed 5.0 V output voltage. It accepts an input supply ranging from 4.5 V to 40 V. The component is housed in a TO-220-5L package and supports through-hole mounting. It functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic controller for simplified design

• Pre-regulators for switching regulators
• Simple step-down DC/DC conversion circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' indicates lead-free status per manufacturer standards. Confirm the physical package matches the TO-220-5L specification required for your board layout. Ensure the operating environment stays within the specified thermal limits. Cross-reference the datasheet revision with your design requirements. Validate that the fixed 5.0 V output aligns with system load needs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5 V output is required with up to 1 A load current. Consider the TO-220-5L package if through-hole assembly is preferred over surface mount alternatives. Evaluate the 40 V maximum input voltage against your source supply. Compare against the LM2591HV series variants if adjustable output or different packaging is needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2591HV family of SIMPLE SWITCHER converters. It shares architectural similarities with other members like the LM2590HV and LM2592HV but differs in output current and voltage specifications. The 'T' suffix typically denotes the specific through-hole package variant within the broader product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Public confirmed substitutes include LM2591HVS-5.0/NOPB (surface mount) and LM2591HVT-ADJ/NOPB (adjustable output). Verify pin compatibility and thermal performance when substituting between package types.
