Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS68000DBTR is determined by the following critical parameters:

• Supply voltage compatibility: 8V ~ 30V input range
• Operating frequency capability: 30kHz ~ 100kHz minimum support
• Dimming functionality: Required for backlight control applications
• Operating temperature range: -40°C ~ 85°C
• Surface mount packaging with compatible footprint dimensions
• RoHS3 compliance and equivalent regulatory certifications

The TPS61196PWPR qualifies as a manufacturer-recommended substitute based on alignment across these core electrical and mechanical parameters. Both devices operate within the same supply voltage window, support dimming control, maintain identical operating temperature specifications, and comply with equivalent environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The TPS61196PWPR is the manufacturer-recommended substitute for the TPS68000DBTR. Selection of this alternative is supported by:

• Identical supply voltage operating range (8V ~ 30V)
• Matching operating temperature specifications (-40°C ~ 85°C)
• Equivalent RoHS3 compliance status
• Active product status, ensuring continued availability and manufacturing support
• Compatible surface mount packaging with identical width dimensions (4.40mm)
• PWM dimming capability meeting the original dimming requirement

The TPS61196PWPR maintains regulatory compliance through ROHS3 certification and REACH unaffected status, consistent with the original component specifications.

Frequently Asked Questions (FAQ)

Q: Can the TPS61196PWPR directly replace the TPS68000DBTR in existing designs?

A: The TPS61196PWPR meets the core electrical parameters (supply voltage, operating temperature, dimming capability) and maintains compatible surface mount packaging dimensions. However, circuit-level integration differences between CCFL controller and LED driver topologies require design review to confirm functional equivalence in the specific application context.

Q: What is the significance of the TPS68000DBTR being marked "Not For New Designs"?

A: This designation indicates the component has been superseded in Texas Instruments' active product line. The TPS61196PWPR, with Active status, represents the current generation alternative and is recommended for new development efforts.

Q: Are the package dimensions identical between these two parts?

A: Both components use surface mount packaging with 0.173" (4.40mm) width specifications. The TPS68000DBTR uses 30-TFSOP while the TPS61196PWPR uses 28-PowerTSSOP. Physical footprint compatibility requires verification against PCB layout specifications.

Q: Do both parts support the same dimming methods?

A: The TPS68000DBTR supports dimming functionality. The TPS61196PWPR specifically supports PWM dimming. Compatibility depends on whether the application circuit implements PWM-based dimming control.

Q: What regulatory certifications apply to both components?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements for industrial and consumer applications.
