 AI Summary | UCC28084DR by Texas Instruments: Half-Bridge, Push-Pull Regulator Positive Output Step-Up/Step-Down DC-DC Controller IC 8-SOIC. | An active sibling from the same family that matches all electrical specifications, package dimension, and temperature ranges, with the exception of having a much faster soft-start of 75 µs instead of 3.5 ms. This is the closest drop-in replacement if the system can accommodate a shorter startup ramp.
| The commercial-grade version of the exact same IC. It maintains all identical electrical and timing characteristics, but is limited to a narrower operating temperature range, making it a viable drop-in for non-harsh environments.
