The UCC28600DR is a simple and reliable integrated, monolithic, fixed-frequency, pulse-width-modulated switching converter IC from Texas Instruments. It is an Offline Switchers IC from its Power Management IC (PMIC) – AC DC Converters portfolio. The device offers cost-effective power conversion and efficiency from the point-of-load to the line voltage with an integrated driver, enabling both Linear and Base DriveTM MOSFET technologies. It is mainly used for low power applications such as computing, networking, and telecom products, automotive and industrial POL applications, motor control, and AC/DC supplies.
The UCC28600DR is designed to offer low cost, small solution size and low noise frequency synchronization. It operates in such a way that the switching transistor is turned on and off at a predetermined frequency and a fixed on-time and off-time (pulse width). From the input power supply, an inductor is placed in series with the load, decreasing voltage but increasing current and is smoothed by a capacitor. The output is regulated by the power-switching transistor and the constant-current sensing technique, which efficiently provides a constant current output. This component is available in a thermally enhanced 28-pin SOIC package and operates over a temperature range of -40 °C to +125 °C.
The UCC28600DR utilizes a single stage power conversion topology approach as it only needs one active device to convert the input voltage source into the output voltage level. Its power switch consists of two transistors, which ensure a low start-up current and hysteretic current loop control, providing a consistent output current. Its maximum output current is 5A, making it applicable for a wide range of low power applications. The device allows its switching frequency to be synchronized to an external clock, which can reach a maximum frequency of up to 500 kHz, while providing an enable function allowing a smooth by helping it become an integrated component in many system power architectures.
The UCC28600DR has an internal switching protection method, which can help protect system operation from short conditions on start-up. It also features an open load detection circuit, which helps protect the load from an over-current condition. In addition, an overtemperature detection circuit helps protect against thermal overloads. The UCC28600DR also has a built-in overvoltage protection circuit and a turn-on delay circuit.
Furthermore, the device integrates all active components that are necessary to create a full-featured switched-mode power supply (SMPS) application. Its advanced control circuitry ensures a stable operation of the switch, assuring a constant output voltage or current through even the toughest load transients. The device\'s monolithic design reduces the complexity of the system and dissipates heat, enabling a lower overall solution cost. It is also designed to have no external compensation components, further simplifying board designs.
In summary, the UCC28600DR is an efficient and reliable solution for low power applications. Its single stage power conversion topology, ability to synchronize to an external clock, wide output current range, switching protection mechanisms, open load detection circuit and overtemperature detection circuit make this an ideal solution for applications such as AC/DC supplies, computing, networking, automotive and industrial point-of-load applications, and motor control. This device is available in a 28-pin SOIC package and provides a wide operating temperature range, making it applicable for use in a variety of applications.
