UCC28086D Equivalent & Substitute Parts

Part Overview

The UCC28086D is a half-bridge, push-pull regulator controller IC manufactured by Texas Instruments, designed for positive output step-up/step-down DC-DC conversion applications. This device functions as a transistor driver with integrated current limit and frequency control features, operating across a 4.1V to 15V supply voltage range. The UCC28086D is currently in active product status with 2100 units available in stock. Identifying equivalent substitute parts becomes necessary when addressing supply chain constraints, inventory optimization, or end-of-life component transitions while maintaining circuit performance and compliance requirements.

Substitute Part Grouping Explanation

Substitute parts for the UCC28086D are determined by strict equivalence across the following critical parameters:

• Package Compatibility: 8-SOIC (0.154", 3.90mm Width) surface mount package
• Electrical Function: Half-bridge, push-pull regulator controller with positive output configuration
• Output Characteristics: 2 outputs, transistor driver type, step-up/step-down capability
• Supply Voltage Range: 4.1V ~ 15V (Vcc/Vdd)
• Switching Frequency: 200kHz operation
• Control Features: Current limit and frequency control functionality
• Synchronous Rectifier: Integrated synchronous rectifier support
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected status

The UCC28084D meets all these criteria and qualifies as a parametric equivalent substitute for the UCC28086D.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The UCC28086D is the recommended choice for new designs and applications requiring long-term supply assurance. This device maintains active product status with Texas Instruments and carries higher inventory availability (2100 units), ensuring sustained component sourcing for production and field deployment.

Substitute Selection: The UCC28084D qualifies as a parametric equivalent substitute when the UCC28086D becomes unavailable or when inventory constraints necessitate alternative sourcing. However, the UCC28084D carries a Last Time Buy product status, indicating that Texas Instruments has discontinued active production. This status restricts its use to applications where existing inventory can satisfy current and near-term demand without requiring future replenishment.

Both devices maintain identical electrical specifications, package geometry, and regulatory compliance certifications (ROHS3 compliant, REACH unaffected). Selection between these parts should prioritize supply chain continuity and production timeline requirements.

Frequently Asked Questions (FAQ)

Q: Can the UCC28084D directly replace the UCC28086D in existing designs?

A: Yes. The UCC28084D is a parametric equivalent substitute with identical electrical specifications, package dimensions (8-SOIC), output configuration, switching frequency (200kHz), supply voltage range (4.1V ~ 15V), and control features (current limit, frequency control). Direct pin-for-pin substitution is supported without circuit modification.

Q: What is the significance of the Last Time Buy status for the UCC28084D?

A: Last Time Buy status indicates that Texas Instruments has ceased active production of the UCC28084D. Existing inventory from authorized distributors represents the final available supply. This part should be selected only when current stock satisfies all anticipated demand, as future replenishment is not available.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the UCC28086D and UCC28084D maintain identical regulatory compliance: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited moisture sensitivity level). Both devices are suitable for applications requiring these certifications.

Q: What package options are available for these controllers?

A: Both the UCC28086D and UCC28084D are supplied exclusively in the 8-SOIC (0.154", 3.90mm width) surface mount package. No alternative package configurations are available for these part numbers.

Q: How do these controllers differ from other Texas Instruments DC-DC controller options?

A: The UCC28086D and UCC28084D are specifically designed for half-bridge and push-pull topologies with positive output step-up/step-down functionality. These devices integrate synchronous rectifier support, current limit, and frequency control features within a compact 8-pin SOIC package, distinguishing them from single-topology or lower-integration alternatives.
