Texas Instruments Inc. (TI) has released a digital power dual synchronous-buck driver with integrated power MOSFETs, protection blocks and monitoring features, which helps save board space and reduce component count by as much as 80 percent compared to industry standards.
The UCD7242 provides designers the flexibility of two independent 10A rails or one 20A rail in a small package, and the highly accurate on-die current sensing element eliminates the need for calibration or temperature compensation. The UCD7242’s input voltage range of 2.2V to 18V supports a variety of applications, such as testing and instrumentation, telecommunications, merchant power supplies, and motherboards with multiple points of load. A dedicated control signal for switching off the low-side MOSFET of each channel makes the UCD7242 highly efficient, even under low load conditions.
TI’s easy-to-use Fusion Digital Power Designer Graphical User Interface (GUI) allows the designer to easily enable the UCD7242’s features when paired with a UCD9xxx controller. The free, downloadable tool simplifies the development process and speeds time-to-market by allowing the designer to configure all device parameters in minutes.
