The Texas Instruments UCC28C44DR is an integrated circuit designed for power management applications, specifically as a current-mode Pulse Width Modulation (PWM) controller. It operates within a voltage range of 9V to 18V and supports topologies such as Boost, Flyback, and Forward converters.
This controller features a maximum duty cycle of 48% and can operate at frequencies up to 1MHz. It includes control features like frequency control and is housed in an 8-SOIC package suitable for surface mounting. The device is designed for industrial applications.
Key electrical characteristics include a maximum startup current of 50µA and a low operating current of 2.3mA at 52kHz. It also offers fast, cycle-by-cycle overcurrent limiting within 35ns and a peak driving current of ±1A. The error amplifier reference is accurate to 2.5V.
The UCC28C44DR is an enhanced replacement for older UCx84x and UCx84xA family devices, offering pin-to-pin compatibility with upgraded functionality. Its compact 8-SOIC package minimizes board space.
