Texas Instruments UCC2806 Low Power, Dual Output, Current Mode PWM Controller UCC2806M

The UCC2806M is a low power, dual output, current mode PWM controller 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, which enhances 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 UCC2806M operates within a temperature range of -40¬8C to 85¬8C and is available in multiple package options, including surface mount configurations. Its dual high-current MOSFET driving outputs and fast current sense loop further enhance its versatility for various applications.
