LM2588T-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2588T-5.0 is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-up, flyback, or forward switching regulator. It operates with an input voltage range of 4 V to 40 V and provides a fixed 5 V output at up to 5 A. The device integrates a 125 V rated switch and supports a switching frequency between 100 kHz and 200 kHz. Designed for through-hole mounting in a TO-220-7 package, it ensures stable performance across an operating temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a high-voltage 125 V rated power switch for robust operation
• Supports versatile topologies including boost, flyback, and forward configurations
• Features internal frequency compensation to simplify external component requirements

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial point-of-load regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' confirms the TO-220-7 through-hole package variant rather than surface-mount options. Confirm RoHS compliance status via the official datasheet, as manufacturing revisions may affect environmental declarations. Ensure the fixed 5.0 V output specification matches the design requirement, as adjustable versions exist within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a wide input range up to 40 V. The TO-220-7 package is suitable for applications needing thermal dissipation capabilities without active cooling. Consider the 100 kHz to 200 kHz switching frequency range for balancing efficiency and passive component size in industrial environments.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the SIMPLE SWITCHER family, the LM2588 series offers integrated solutions for non-isolated and isolated DC-DC conversion. The LM2588T-5.0 specifically targets applications requiring higher current handling in a through-hole format, distinguishing it from surface-mount variants like the LM2588S series.
