The UCC2806PWTR from Texas Instruments is a BiCMOS PWM controller designed for low-power applications. It features a dual-output configuration and operates in current-mode control, offering benefits such as simpler loop closing and pulse-by-pulse current limiting.
Key electrical specifications include a maximum operating current of 1.4mA and a startup current as low as 50μA typical. The device can deliver ±0.5A peak output current with a circuit delay of 125ns. It supports a wide input voltage range of 8V to 14.5V and operates at frequencies up to 47kHz, with a maximum duty cycle of 50%.
This controller is suitable for various topologies including Boost, Flyback, and Forward converters. It offers control features such as current limit, enable, and frequency control. The UCC2806PWTR is available in a 16-TSSOP surface mount package and operates within an industrial temperature range of -40°C to 85°C.
Its architecture is a BiCMOS version of the UC3846 family, providing improved switching frequency capability while reducing bias current. This makes it a versatile choice for applications ranging from off-line power supplies to battery-operated portable equipment.
