Texas Instruments UCC2813-5 Low Power Economy BiCMOS Current Mode PWM UCC2813DTR-5G4

The UCC2813-5 is a low-power BiCMOS current mode PWM controller designed for use in switch mode power supplies, DC-DC converters, and battery-operated power supplies. It features a typical starting supply current of 100¬µA and an operating supply current of 500¬µA, allowing for efficient power management. The device operates at frequencies up to 1MHz and includes internal soft start and fault soft start capabilities, enhancing system reliability. This controller provides a 1A totem-pole output with a typical response time of 70ns from current-sense to gate-drive output, which is beneficial for fast switching applications. The UCC2813-5 has a 1.5% tolerance voltage reference and is specified for operation over a temperature range of -40¬8C to 85¬8C. It shares the same pinout as other devices in the UCC3802 and UC3842 families, facilitating design integration. The UCC2813-5 is suitable for applications requiring a compact solution with minimal external components.
