UCC2808N-2 Equivalent & Substitute Parts

Part Overview

The UCC2808N-2 is a Push-Pull Regulator Positive Output Step-Up/Step-Down DC-DC Controller IC manufactured by Texas Instruments in 8-PDIP packaging. This device functions as a transistor driver for step-up/step-down topologies with a single output phase and frequency control capabilities. The UCC2808N-2 is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and production continuity. Equivalent parts maintain identical electrical and mechanical specifications while offering improved availability or alternative packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC2808N-2 is determined by strict equivalence across the following critical parameters: output type (transistor driver), function (step-up/step-down), output configuration (positive), topology (push-pull), number of outputs (2), output phases (1), supply voltage range (4.1V ~ 15V), switching frequency (194kHz), duty cycle maximum (49%), control features (frequency control), and operating temperature range (-40°C ~ 85°C).

The identified substitutes maintain all electrical specifications while differing in packaging and product status. The UCC2808D-2 provides an active-status alternative in surface-mount 8-SOIC packaging. The UCC2808AN-2 maintains the through-hole 8-DIP form factor with obsolete status classification. Both substitutes share identical electrical performance parameters and compliance certifications with the main part.

Engineering Selection Recommendations

For through-hole PCB designs requiring pin-compatible replacement, the UCC2808AN-2 provides direct substitution with identical 8-DIP packaging and electrical specifications. Both the UCC2808N-2 and UCC2808AN-2 share obsolete product status.

For new designs or production transitions, the UCC2808D-2 is the recommended selection. This part maintains all electrical and functional equivalence while offering active product status and surface-mount 8-SOIC packaging. The UCC2808D-2 provides superior long-term availability and supply chain stability. All three parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, ensuring regulatory and environmental compatibility across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can the UCC2808D-2 replace the UCC2808N-2 in existing through-hole designs?

A: Electrical substitution is valid; however, the UCC2808D-2 uses surface-mount 8-SOIC packaging versus the through-hole 8-DIP form factor of the UCC2808N-2. PCB layout modification and adapter solutions are required for mechanical integration.

Q: What is the primary difference between UCC2808N-2 and UCC2808AN-2?

A: Both parts are electrically and mechanically identical, sharing 8-DIP through-hole packaging and identical electrical specifications. The distinction is product status classification; both are obsolete.

Q: Are all three parts RoHS compliant?

A: Yes. The UCC2808N-2, UCC2808D-2, and UCC2808AN-2 are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: Which substitute offers the best long-term availability?

A: The UCC2808D-2 is classified as active product status, providing superior availability and supply chain continuity compared to the obsolete UCC2808N-2 and UCC2808AN-2.

Q: Do all substitutes operate at the same switching frequency?

A: Yes. All three parts operate at 194kHz switching frequency with 49% maximum duty cycle and identical supply voltage range of 4.1V ~ 15V.
