Key Parameters

Substitute Part Grouping Explanation

The UCC28084DR qualifies as a parametric equivalent to the UCC28086DR based on strict alignment across all critical electrical and mechanical parameters. Substitution eligibility is determined by the following key parameters:

• Output Type: Transistor Driver
• Function: Step-Up/Step-Down
• Topology: Half-Bridge, Push-Pull
• Number of Outputs: 2
• Voltage Supply Range: 4.1V ~ 15V
• Switching Frequency: 200kHz
• Duty Cycle (Max): 49%
• Synchronous Rectifier: Yes
• Control Features: Current Limit, Frequency Control
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The UCC28084DR maintains identical electrical specifications and mechanical compatibility, enabling direct substitution in applications where the UCC28086DR is specified.

Parameter Comparison
