LM2592HVT-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2592HVT-5.0/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-down voltage regulator with a fixed 5 V output. It supports an input voltage range of 4.5 V to 60 V and delivers up to 2 A of output current. Operating at a typical switching frequency of 150 kHz, the device utilizes a TO-220-5 package for surface mount or through-hole installation. It features internal frequency compensation and a fixed 52 kHz oscillator, ensuring stable performance across a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates the TO-220 package variant distinct from the SMD 'VS' version. Confirm the '-5.0' designation ensures a fixed 5 V output rather than adjustable models. Cross-reference the manufacturer part number against official TI databases to ensure RoHS compliance and current production status before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from high input voltages up to 60 V. The TO-220 package offers robust thermal dissipation capabilities suitable for higher current loads compared to smaller surface-mount alternatives. Ensure the application environment remains within the specified -40°C to +125°C operating temperature range for optimal reliability.
