Texas Instruments UCC3809N-1 is a high-performance, low-power current-mode PWM controller designed for offline power supply applications. This 8-PDIP packaged device supports multiple topologies including Boost, Buck, Flyback, and Forward converters, operating at a switching frequency of up to 1MHz. Optimized for efficiency, it features a 70% maximum duty cycle and includes integrated soft-start circuitry for controlled power-up sequences. The UCC3809N-1 operates within a supply voltage range of 8V to 19V, with a typical startup voltage of 15V. Its through-hole mounting type and isolated output make it suitable for demanding applications in industrial automation, consumer electronics, and telecommunications. The wide operating temperature range of -55°C to 150°C ensures reliability in harsh environments.
