Is there a pin-compatible replacement for UCC28180DR?

Several 8-pin SOIC PFC controllers like the Infineon ICE2/ICE3 series are potential candidates, but pin-to-pin compatibility is not guaranteed without a direct comparison of the datasheets. Review of the pin functions is mandatory.

What risks should I check before replacing UCC28180DR?

First, verify the pinout is identical. Second, ensure the candidate's switching frequency characteristics (fixed vs. programmable, range) meet your design needs. Finally, check that the operating temperature range and other electrical parameters are acceptable for your application.

UCC28180DR Alternatives, Datasheet & Cross Reference | Texas Instruments

UCC28180DR is an 8-pin CCM boost PFC controller. While no drop-in replacements are confirmed, several functional alternatives from Infineon exist that share the same package and operating mode but differ in switching frequency or temperature range. Pinout verification is requi...

AI replacement insight

Package risklow

SOIC-8/PG-DSO-8 packages are highly standardized.

Electrical riskmedium

Differences in frequency and temperature require engineering review.

Firmware risklow

Not applicable for this analog controller.

Can it be replaced directly?

No direct, pin-compatible replacement for UCC28180DR can be confirmed without datasheet pinout verification. Functional alternatives in the same package exist but require careful review.

Best replacement path

ICE3PCS03G offers the most similar switching frequency range but has a narrower operating temperature. All candidates require pinout verification.

Main risk

The primary risk is pinout incompatibility. Secondary risks include differences in switching frequency and operating temperature range.

Recommended alternatives

Strong functional alternative with very similar switching frequency, but a narrower temperature range. Pinout must be verified.

Application & sourcing insights

Questions & answers

ICE3PCS03G is a strong functional alternative due to its similar CCM operation and wide switching frequency range. However, its operating temperature starts at -25°C, not -40°C, and its pinout must be verified against the UCC28180DR before use.
