LM2588T-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2588T-3.3 is a SIMPLE SWITCHER step-up/flyback switching voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 4 V to 40 V and provides a fixed 3.3 V output. The device supports up to 6.5 A output current in flyback configurations and utilizes a TO-220-7 package for through-hole mounting. It features a switch frequency of 200 kHz, operates within a temperature range of -40°C to +125°C, and includes integrated shutdown functionality.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates the TO-220-7 through-hole package variant. Confirm the '-3.3' suffix denotes the fixed 3.3 V output version. Check RoHS compliance status as some older revisions may differ. Ensure the supplier provides the official Texas Instruments datasheet for the exact part number to verify pinout and thermal characteristics before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required from a wide input voltage range up to 40 V. The TO-220-7 package is suitable for higher current applications where through-hole mounting is preferred for mechanical stability. Consider the 200 kHz switching frequency for balancing efficiency and external component size. Verify that the load requirements do not exceed the 6.5 A capability in flyback mode.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2588 belongs to the SIMPLE SWITCHER family of high-current regulators. It is designed for versatile topologies including boost, flyback, and forward converters. The T-series designation typically refers to the TO-220-7 package variant, distinguishing it from surface-mount options like the S or SX series. This family emphasizes ease of design with minimal external components.
