UCC3813D-0

Designed for high efficiency and precise regulation, the UCC3813D-0 is a high-performance current mode PWM controller that offers a wide input voltage range of 8V to 18V, providing flexibility for various power supply designs. Its low start-up current and operating current enable energy-efficient operation, making it a suitable choice for power-conscious applications. The device features a precise voltage reference, error amplifier, and PWM comparator for accurate regulation, as well as adjustable switching frequency and a programmable soft-start function for smooth startup, reducing stress on components. The current mode control architecture ensures stability and fast transient response, catering to applications with dynamic load requirements. Additionally, the UCC3813D-0 incorporates protection features such as overcurrent protection and undervoltage lockout, enhancing system reliability and safety. Its small-outline SOIC-8 package further adds to its versatility, making it suitable for space-constrained applications
