LM2575TV-ADJG Equivalent & Substitute Parts

Part Overview

The LM2575TV-ADJG is an active buck switching regulator IC from onsemi, designed for step-down voltage conversion with positive adjustable output. This through-hole mounted component operates across a wide input voltage range of 4.75V to 40V and delivers 1A output current at adjustable voltage levels from 1.23V to 37V. The device is actively produced and widely used in power management applications requiring compact, efficient DC-DC conversion.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent performance specifications across different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2575TV-ADJG is determined by strict alignment of the following critical parameters:

• Topology & Function: Buck switching regulator with step-down capability
• Output Configuration: Positive adjustable output
• Package & Mounting: TO-220-5 Formed Leads, through-hole mounting
• Output Voltage Range: Minimum 1.23V adjustable output capability
• Output Current: 1A rated output current
• Switching Frequency: 52kHz operation
• Operating Temperature Range: -40°C to 125°C junction temperature
• Regulatory Compliance: ROHS3 compliant, REACH unaffected status

The TL2575HV-ADJIKV from Texas Instruments meets all substitution criteria. Both devices share identical topology, output configuration, package format, switching frequency, and temperature operating range. The substitute part accommodates higher maximum input voltage (60V vs. 40V) and higher maximum output voltage (57V vs. 37V), making it suitable for applications within the LM2575TV-ADJG's specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the LM2575TV-ADJG and TL2575HV-ADJIKV are active production devices with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The TL2575HV-ADJIKV operates within the electrical specifications of the LM2575TV-ADJG for all standard application circuits. The higher voltage ratings of the Texas Instruments device provide additional design margin without compromising performance in circuits designed for the onsemi part's maximum ratings.

Selection between these parts should be based on availability, lead time, and supply chain requirements. Both devices are suitable for direct substitution in existing designs without circuit modification when operating within the LM2575TV-ADJG's specified parameter limits.

Frequently Asked Questions (FAQ)

Q: Can the TL2575HV-ADJIKV replace the LM2575TV-ADJG in existing circuit designs?

A: Yes. The TL2575HV-ADJIKV is electrically and mechanically compatible. Both devices share identical output voltage adjustment range (1.23V to 37V), output current rating (1A), switching frequency (52kHz), operating temperature range (-40°C to 125°C), and TO-220-5 package format. No circuit modifications are required.

Q: What is the significance of the higher input voltage rating on the TL2575HV-ADJIKV?

A: The TL2575HV-ADJIKV accepts input voltages up to 60V compared to 40V for the LM2575TV-ADJG. This extended rating provides additional design flexibility for applications with variable input sources. Circuits designed for the LM2575TV-ADJG's 40V maximum input operate identically on the substitute part.

Q: Are both parts suitable for new designs?

A: Yes. Both the LM2575TV-ADJG and TL2575HV-ADJIKV are active production devices. Either part is appropriate for new designs based on availability and supply chain considerations.

Q: Do these parts require different PCB layouts or thermal management approaches?

A: No. Both devices use identical TO-220-5 Formed Leads packaging and share the same thermal characteristics. PCB layouts and thermal management strategies designed for one part apply directly to the other.

Q: What compliance certifications apply to both parts?

A: Both the LM2575TV-ADJG and TL2575HV-ADJIKV are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for industrial applications.
