LM3538TMX/NOPB Equivalent & Substitute Parts

Part Overview

The LM3538TMX/NOPB is an LED Driver IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This device functions as an 8-output DC-DC regulator utilizing switched capacitor (charge pump) topology with PWM dimming capability, designed for backlight applications. The part is currently in active production status with 731 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where component availability or supply chain requirements necessitate alternative sourcing.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LM3538TMX/NOPB, LM3537TME/NOPB, and LM3538TME/NOPB—are manufactured by Texas Instruments and maintain active production status. Each part carries identical electrical specifications, package configurations, and regulatory certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts is determined by availability and supply chain requirements rather than technical performance differences. The LM3538TMX/NOPB and LM3538TME/NOPB share the same base product number (LM3538), while the LM3537TME/NOPB represents an alternative base product (LM3537) with equivalent functional characteristics. All parts are suitable for direct substitution in backlight driver applications requiring 8-channel LED regulation with PWM dimming control.

Frequently Asked Questions (FAQ)

Q: Can LM3537TME/NOPB replace LM3538TMX/NOPB in production designs?

A: Yes. Both parts maintain identical electrical parameters, output configuration, supply voltage range, and package specifications. The difference in base product number (LM3537 vs. LM3538) does not affect functional compatibility when all electrical and mechanical parameters are equivalent.

Q: What is the difference between the TMX and TME package designations?

A: TMX and TME designations indicate different manufacturing codes or date codes assigned by Texas Instruments. Both are supplied in 30-DSBGA packages with identical electrical specifications and are functionally interchangeable.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts use the 30-DSBGA package with identical pin configurations and mounting requirements. PCB layouts designed for one part are directly compatible with the others without modification.

Q: Do these parts require different handling or storage procedures?

A: No. All parts share Moisture Sensitivity Level 1 (Unlimited), indicating identical moisture handling requirements and unlimited shelf life under standard storage conditions.

Q: Can these parts be mixed in the same production batch?

A: Yes. All parts are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements. They can be used interchangeably within the same assembly process.
