The UCC3809N-1 from Texas Instruments is an integrated circuit designed for economy low-power switching power supplies. It contains essential control and drive circuitry for off-line and isolated DC-to-DC applications, minimizing external component count.
Key features include a user-programmable soft start with active low shutdown, a user-programmable maximum duty cycle, and an accessible 5V reference. The device also incorporates undervoltage lockout (UVLO) to ensure reliable operation. It can operate at frequencies up to 1MHz and includes a 0.4A source/0.8A sink FET driver.
This controller is suitable for various topologies including Boost, Buck, Flyback, and Forward converters. It operates within a supply voltage range of 8V to 19V and has a typical duty cycle of 70%. The UCC3809N-1 is available in an 8-pin PDIP package, making it suitable for applications where board space is a consideration.
The device offers features like frequency control and soft start, along with undervoltage lockout thresholds and hysteresis levels tailored for off-line and DC-to-DC systems. Its low startup current of less than 100µA contributes to its economy and low-power characteristics.
