Frequently Asked Questions
What is the maximum switching frequency of the UCC3807N-1G4?
The UCC3807N-1G4 supports switching frequencies up to 1000 kHz (1 MHz), which is significantly higher than conventional 100-300 kHz PWM controllers. This high operating frequency allows the use of smaller magnetics and filter capacitors, reducing overall converter size and cost.
What control mode does the UCC3807N-1G4 use?
The UCC3807N-1G4 uses current-mode pulse width modulation (PWM) control, which provides inherent cycle-by-cycle current limiting and improved transient response compared to voltage-mode control. Current-mode control also simplifies loop compensation and enhances power supply reliability against overload conditions.
What is the input voltage range for the UCC3807N-1G4?
The UCC3807N-1G4 operates from an input voltage range of 7.5V to 12V with a nominal operating voltage of 10V. This makes it compatible with standard 12V and 10V auxiliary power rails commonly found in ATX power supplies, telecom equipment, and industrial control systems.
What package does the UCC3807N-1G4 use?
The UCC3807N-1G4 is housed in an 8-pin Plastic Dual-In-Line Package (PDIP), designated by JESD-30 code R-PDIP-T8. This through-hole package is suitable for breadboard prototyping and traditional PCB assembly, and is compatible with standard 8-pin DIP IC sockets.
Is the UCC3807N-1G4 suitable for flyback converter designs?
Yes, the UCC3807N-1G4 is well-suited for flyback converter designs, where its current-mode PWM control provides excellent line and load regulation along with built-in cycle-by-cycle current limiting for transformer protection. Its 1A gate drive output enables efficient switching of external MOSFETs in primary-side switch configurations up to 1 MHz.
