DESCRIPTION
· The UCC35705 and UCC35706 are 8-pin voltage mode primary side controllers designed for high-speed operation.
· They are core components in high-performance isolated and non-isolated power converters.
· These devices feature an integrated oscillator with voltage feed-forward compensation for enhanced performance.
· They offer fast over-current protection with a 25-ns current sense to output delay time.
· The IC includes a programmable maximum duty cycle clamp for added protection, which can be disabled for maximum duty cycle operation.
· Two UVLO options are available: UCC35705 for DC-to-DC converters and UCC35706 for offline applications.
· Available in 8-pin MSOP, SOIC, and PDIP packages.
FEATURES
· Operates at frequencies greater than 4 MHz.
· Integrated oscillator with voltage feed-forward compensation.
· Supports input voltage ranges greater than 4:1.
· Fast 25-ns current limit delay.
· Programmable maximum duty cycle clamp.
· Optocoupler interface for isolation.
· Low start-up current of 50 μA.
· Operating current of 4.2 mA at 1 MHz.
· Compact 8-pin MSOP package minimizes board area and height.
APPLICATIONS
· High-performance isolated and non-isolated power converters.
· DC-to-DC converters (UCC35705).
· Offline power supplies (UCC35706).
