LM2576HVT-15 Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments LM2576HVT-15 is a Power Management IC in the Step-Down (Buck) Regulator category, designed for converting higher DC voltages into a regulated fixed 15V output at up to 3A. It is housed in a TO-220-5 package in through-hole configuration. The part status is listed as obsolete, necessitating the selection of suitable substitute parts for ongoing designs, maintenance, and inventory replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on the following key electrical and mechanical parameters:

• Step-Down (Buck) topology
• Positive fixed 15V output voltage
• Through-hole TO-220-5 package
• Output configuration, type, and number of outputs
• Compatible input voltage range
• Frequency specification
• Maximum operating temperature range
• Output current rating

Only parts matching these electrical and mechanical characteristics are included. RoHS and REACH compliance, as well as product status, are considered where provided.

Parameter Comparison

Engineering Selection Recommendations

The LM2576HVT-15 is obsolete. Substitute parts LM2576HVT-15/LF03 and LM2576HVT-15/NOPB are listed as active and provide matching electrical and mechanical parameters. Both offer RoHS3 and REACH compliance for enhanced environmental compatibility compared to the original. LM2575T-15G shares major functional attributes but features a reduced output current rating (1A) and a lower input voltage maximum (40V), and is also obsolete. Selection should be guided by the product status and compliance data provided for your application requirements.

Frequently Asked Questions (FAQ)

Q1: Are LM2576HVT-15/LF03 and LM2576HVT-15/NOPB direct substitutes for LM2576HVT-15?
Yes. Both are configured as step-down buck regulators with identical output voltage, output current, operating temperature range, electrical performance, and package type.

Q2: Does the TO-220-5 Formed Leads package affect mounting?
The TO-220-5 Formed Leads package differs by lead shape but maintains the same fundamental footprint and through-hole compatibility. Verify assembly requirements for lead configuration.

Q3: Can LM2575T-15G replace LM2576HVT-15?
LM2575T-15G matches most electrical and mechanical criteria but offers a maximum output current of 1A and a lower maximum input voltage (40V). The suitability depends on required output current and input voltage.

Q4: Which substitute is RoHS compliant?
LM2576HVT-15/LF03, LM2576HVT-15/NOPB, and LM2575T-15G are listed as ROHS3 Compliant. LM2576HVT-15 is RoHS non-compliant.

Q5: Are thermal, switching frequency, or topological characteristics consistent across substitutes?
All listed alternatives maintain a -40°C to 125°C junction temperature range, a 52kHz switching frequency, and buck regulator topology per the provided specifications.
