The UCC3813N-0 is a high-speed, low-power integrated circuit designed for off-line and DC-to-DC fixed-frequency current-mode switching power supplies. It features a minimal parts count, making it suitable for various applications including switch-mode power supplies, DC-DC converters, and battery-operated power supplies. The device includes internal full-cycle soft start and leading-edge blanking for the current-sense input, enhancing its performance and reliability. This controller operates with a typical starting supply current of 100 ¬µA and a typical operating supply current of 500 ¬µA, supporting operation up to 1 MHz. It provides a 1-A totem-pole output and has a typical response time of 70 ns from current-sense to gate-drive output. The UCC3813N-0 is specified for operation in a temperature range of 0¬8C to 70¬8C and is available in multiple package options including PDIP, SOIC, and TSSOP. Its pin configuration is compatible with other devices in the UCCx813 family, facilitating design integration.
