LP8720TLE-B/NOPB Equivalent & Substitute Parts

Part Overview

The LP8720TLE-B/NOPB is a PMIC (Power Management Integrated Circuit) from Texas Instruments that integrates one synchronous step-down (buck) converter and five linear (LDO) regulators in a single 20-DSBGA package. This six-output voltage regulator operates at 2MHz switching frequency and supports input voltages from 2.7V to 4.5V, making it suitable for multi-rail power distribution in portable and embedded applications.

The LP8720TLE-B/NOPB is classified as obsolete. Equivalent substitute parts are available to maintain design continuity and ensure supply chain reliability for applications currently using this component.

Substitute Part Grouping Explanation

Substitute parts for the LP8720TLE-B/NOPB are determined by strict equivalence across the following electrical and mechanical parameters:

Topology: Step-Down (Buck) Synchronous (1), Linear (LDO) (5)
Number of Outputs: 6
Switching Frequency: 2MHz
Output voltage and current specifications for all three primary outputs
Supply voltage range: 2.7V ~ 4.5V
Operating temperature range: -40°C ~ 85°C
Package type: 20-DSBGA
Sequencer functionality: Present

All substitute parts maintain identical electrical performance and pinout compatibility. Differences are limited to manufacturer designation, packaging format (bulk vs. tape & reel), and product status (active vs. obsolete).

Engineering Selection Recommendations

LP8720TLE/NOPB (National Semiconductor, Bulk Packaging)

This part is an active substitute with identical electrical specifications and pinout. It is supplied in bulk packaging format. Selection of this part is appropriate for applications where packaging format does not impose constraints and where active product status is required for long-term supply assurance.

LP8720TLX/NOPB (Texas Instruments, Tape & Reel Packaging)

This part is an active substitute from the original manufacturer (Texas Instruments) with identical electrical specifications and pinout. It is supplied in tape & reel format, which is standard for automated assembly processes. This part is recommended for production environments requiring automated component handling and where active product status and RoHS3 compliance are required.

Frequently Asked Questions (FAQ)

Q: Can LP8720TLE/NOPB and LP8720TLX/NOPB be used interchangeably with LP8720TLE-B/NOPB?

A: Yes. Both substitute parts maintain identical electrical performance, output specifications, switching frequency, and pinout. The primary differences are product status (active vs. obsolete) and packaging format (bulk vs. tape & reel). Electrical and mechanical compatibility is complete.

Q: What is the difference between bulk and tape & reel packaging?

A: Bulk packaging supplies components loose or in trays, suitable for manual handling or small-volume applications. Tape & reel packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment used in production environments.

Q: Why is the LP8720TLE-B/NOPB classified as obsolete?

A: The LP8720TLE-B/NOPB is listed as obsolete by the manufacturer. Active substitute parts (LP8720TLE/NOPB and LP8720TLX/NOPB) are available to support existing designs and ensure supply continuity.

Q: Are there any compliance differences between the substitute parts?

A: LP8720TLX/NOPB is specified as ROHS3 Compliant and REACH Unaffected. LP8720TLE/NOPB compliance specifications are not provided in the available data. For applications with specific regulatory requirements, LP8720TLX/NOPB is the recommended choice.

Q: Can I use these parts in new designs?

A: LP8720TLE/NOPB and LP8720TLX/NOPB are both active products and are suitable for new designs. LP8720TLE-B/NOPB, being obsolete, is not recommended for new designs.
