Frequently Asked Questions
What is the switching frequency range of the UCC28070APWR?
The UCC28070APWR supports an extended switching frequency range from 10kHz to 300kHz, giving designers flexibility to optimize the trade-off between magnetics size, switching losses, and EMI filter requirements in PFC stage designs.
What input voltage does the UCC28070APWR require?
The UCC28070APWR requires a bias supply voltage between 10.8V and 21V, with a nominal operating voltage of 12V. This makes it directly compatible with standard 12V auxiliary rails commonly available in ATX and server power supply platforms.
What are the typical applications for the UCC28070APWR?
The UCC28070APWR is designed for two-phase interleaved continuous conduction mode (CCM) PFC in high-power AC/DC converters. Typical applications include server and workstation power supplies, telecom rectifiers, industrial motor drives, UPS systems, and solar inverter front-ends requiring high power factor and low THD.
What package does the UCC28070APWR come in?
The UCC28070APWR is available in a 20-pin Small Outline IC (SOIC) package, also identified by JEDEC code R-PDSO-G20. It is RoHS-compliant and lead-free (Pb-free), suitable for modern PCB assembly processes.
What is the difference between UCC28070APWR and UCC28070PWR?
The UCC28070APWR is an enhanced version of the UCC28070PWR with improved performance characteristics, including better gate drive timing and refined oscillator accuracy. Both implement two-phase interleaved CCM PFC control, but the 'A' variant offers tighter specifications suitable for higher-precision power supply designs.
