TLC5960DA LED Driver Controller Equivalent & Substitute Parts

Part Overview

The TLC5960DA is an active LED driver controller IC manufactured by Texas Instruments, designed for 8-output DC-DC control applications with analog and PWM dimming capabilities. This Surface Mount device operates across a 10V to 28V supply range and is commonly used in backlight applications. The part is in active production status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when inventory constraints, lead time requirements, or specific application parameters necessitate alternative component selection while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC5960DA is determined by the following critical parameters:

• Functional Type: DC DC Controller with 8-output LED driver capability
• Dimming Support: Analog and/or PWM dimming functionality
• Supply Voltage Compatibility: Minimum 10V to maximum 28V operating range
• Package Form Factor: Surface Mount TSSOP configuration
• Application Domain: Backlight LED driver control
• Compliance Requirements: RoHS3 compliance and REACH unaffected status

The MP3373GM-Z qualifies as a manufacturer-recommended substitute based on matching functional classification, 8-output architecture, surface mount TSSOP packaging, backlight application alignment, and equivalent compliance certifications. Differences in supply voltage range, topology classification, and operating temperature specifications are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Both the TLC5960DA and MP3373GM-Z maintain active product status with equivalent RoHS3 compliance and REACH unaffected certifications, ensuring regulatory alignment for industrial and consumer backlight applications. The TLC5960DA operates within a 10V to 28V supply window with combined analog and PWM dimming support. The MP3373GM-Z extends the maximum supply voltage to 40V and provides PWM dimming functionality within a -40°C to 125°C operating range, offering broader thermal performance margins. Package form factor differences (38-TSSOP versus 28-TSSOP) require PCB layout verification prior to substitution. Selection between these parts should be based on specific application supply voltage requirements, dimming control architecture, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the MP3373GM-Z directly replace the TLC5960DA in existing designs?

A: Direct replacement requires verification of three factors: (1) PCB layout compatibility with the different TSSOP package widths (38-TSSOP versus 28-TSSOP), (2) application supply voltage operating range alignment with the 9V to 40V specification of the MP3373GM-Z, and (3) dimming control circuit compatibility, as the MP3373GM-Z supports PWM dimming only, whereas the TLC5960DA supports both analog and PWM dimming modes.

Q: What are the key differences in supply voltage specifications?

A: The TLC5960DA operates from 10V to 28V, while the MP3373GM-Z operates from 9V to 40V. Applications requiring supply voltages below 10V or above 28V may benefit from the extended range of the MP3373GM-Z. Applications with fixed supply voltages within the 10V to 28V window are compatible with both parts.

Q: How do the package differences affect substitution?

A: The TLC5960DA uses a 38-TSSOP package (0.240" width, 6.10mm), while the MP3373GM-Z uses a 28-TSSOP package (0.173" width, 4.40mm). The MP3373GM-Z package is physically smaller. PCB footprint redesign is required for substitution; direct pin-to-pin replacement on existing layouts is not possible.

Q: Are both parts suitable for backlight applications?

A: Yes. Both the TLC5960DA and MP3373GM-Z are specified for backlight applications and maintain equivalent compliance certifications (RoHS3, REACH unaffected) and moisture sensitivity levels (MSL 2, 1 Year).

Q: What is the significance of the topology difference?

A: The MP3373GM-Z is classified as a Step-Up (Boost) topology controller, while the TLC5960DA topology is not specified in the provided parameters. Application circuit design and external component selection must align with the specified topology of the selected part.
