Texas Instruments UCC1806 Low Power, Dual Output, Current Mode PWM Controller UCC1806J883B

The UCC1806J883B is a low power, dual output, current mode PWM controller from Texas Instruments, designed for applications such as off-line power supplies and battery-operated portable equipment. It features a maximum operating current of 1.4 mA and a startup current of 100 OºA, making it suitable for low power applications. The controller supports a peak output current of ¬±0.5 A and has a circuit delay of 125 ns, enhancing its responsiveness. This device is part of the BiCMOS version of the UC3846 family, offering improved performance with a familiar architecture. It allows for easier parallelability and includes benefits such as pulse-by-pulse current limiting and voltage feed-forward. The UCC1806 operates over a temperature range of -55¬8C to 125¬8C and is available in multiple package options, including through-hole and surface mount configurations. It is suitable for both commercial and military applications, providing versatility in design.
