LM5022MM Equivalent & Substitute Parts

Part Overview

The LM5022MM is a Boost/SEPIC Regulator Controller IC manufactured by Texas Instruments, designed for positive output step-up and step-up/step-down DC-DC conversion applications. This device operates as a transistor driver with integrated frequency control and soft start features, supporting supply voltages from 6V to 60V with a maximum duty cycle of 95%. The LM5022MM is currently in Last Time Buy status, making equivalent substitute parts necessary for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitute parts for the LM5022MM are classified based on strict electrical and mechanical parameter equivalence. All substitute parts maintain identical core functionality as Boost/SEPIC regulator controllers with the same output type, topology, and control features. Substitution eligibility is determined by the following criteria:

Core Electrical Parameters (Must Match):

• Function: Step-Up, Step-Up/Step-Down
• Topology: Boost, SEPIC
• Output Type: Transistor Driver
• Output Configuration: Positive
• Number of Outputs: 1
• Output Phases: 1
• Voltage - Supply (Vcc/Vdd): 6V ~ 60V
• Duty Cycle (Max): 95%
• Synchronous Rectifier: No
• Clock Sync: Yes
• Control Features: Frequency Control, Soft Start
• Operating Temperature: -40°C ~ 125°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width)
• Supplier Device Package: 10-VSSOP

Allowable Variations:

• Switching Frequency range may extend beyond 200kHz ~ 990kHz (200kHz ~ 2.24MHz acceptable)
• Packaging format (Cut Tape vs. Tape & Reel)
• Product Status (Active variants acceptable for Last Time Buy part)
• Automotive grade and AEC-Q100 qualification (additional certifications do not prevent substitution)

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the LM5022MM. Selection among available substitutes should be based on the following criteria:

For Standard Industrial Applications: LM5022MM/NOPB, LM5022MME/NOPB, and LM5022MMX/NOPB are direct equivalents with Active product status. These parts are suitable for applications not requiring automotive qualification. LM5022MM/NOPB offers the highest inventory availability at 17,400 units.

For Automotive Applications: LM5022QDGSRQ1 and LM5022QDGSTQ1 are automotive-grade variants with AEC-Q100 qualification. These parts are required for automotive designs and meet additional reliability and qualification standards. LM5022QDGSTQ1 provides significantly higher inventory availability (109,354 units) in Tape & Reel packaging format.

Packaging Considerations: LM5022QDGSTQ1 is supplied in Tape & Reel (TR) format, while all other substitutes are available in Cut Tape (CT) & Digi-Reel® format. Tape & Reel packaging is standard for high-volume production environments.

Switching Frequency Range: LM5022QDGSRQ1 and LM5022QDGSTQ1 support an extended switching frequency range of 200kHz ~ 2.24MHz compared to the standard 200kHz ~ 990kHz range of other variants. This extended range does not affect compatibility for applications operating within the standard range.

Frequently Asked Questions (FAQ)

Q: Can I substitute LM5022MM with LM5022MM/NOPB? A: Yes. LM5022MM/NOPB is a direct equivalent with identical electrical and mechanical parameters. The primary difference is product status (Active vs. Last Time Buy) and higher inventory availability.

Q: What is the difference between LM5022MME/NOPB and LM5022MMX/NOPB? A: Both parts are parametric equivalents with identical electrical specifications and Active product status. The suffix designations (E and X) indicate different manufacturing or qualification batches. Both are suitable for the same applications.

Q: Can I use automotive-grade LM5022QDGSTQ1 in non-automotive applications? A: Yes. Automotive-grade parts meet or exceed industrial specifications and are fully compatible with non-automotive designs. However, automotive-grade parts typically command a price premium and should be selected only when automotive qualification is required.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Cut Tape (CT) & Digi-Reel® packaging is suitable for lower-volume production and manual assembly. Tape & Reel (TR) packaging is optimized for high-volume automated assembly lines. Both formats contain identical components; packaging format selection depends on production volume and assembly equipment.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I use LM5022QDGSRQ1 instead of LM5022QDGSTQ1? A: Yes. Both are automotive-grade AEC-Q100 qualified variants with identical electrical parameters. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and inventory availability. Selection depends on production volume and assembly process requirements.

Q: What does the extended switching frequency range (200kHz ~ 2.24MHz) in automotive variants mean for my design? A: The extended range provides additional flexibility for frequency selection in automotive applications. If your design operates within the standard 200kHz ~ 990kHz range, both standard and automotive variants are functionally equivalent. The extended range does not affect compatibility.
