UCC28950QPWRQ1 - Brand New Texas Instruments DC DC Switching Controllers
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
Description
The UCC28950-Q1 enhanced phase- shifted controller builds upon Texas Instruments' industry-standard UCCx895 phase-shifted controller family with enhancements that offer best-in-class efficiency in today's high-performance power systems. The UCC28950-Q1 implements advanced control of the full bridge along with active control of the synchronous-rectifier output stage. The primary-side signals allow programmable delays to ensure ZVS operation over wide load-current and input-voltage ranges, while the load current naturally tunes the secondary-side switching delays of the synchronous rectifiers， maximizing overall system efficiency.
