TI unveils fully-integrated Fusion Digital Power™ dual power driver with onboard power MOSFETs

PRNewswire
Feb 18, 2010

DALLAS, Feb. 18 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced 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 10-A rails or one 20-A rail in a small package. The highly accurate on-die current sensing element eliminates the need for calibration or temperature compensation. The UCD7242's input voltage range of 2.2 V to 18 V supports a variety of applications, such as testing and instrumentation, telecommunications, merchant power supplies, and motherboards with multiple points of load. To order samples see: www.ti.com/ucd7242-pr.

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.

Key features and benefits of the UCD7242

  • Matched drivers and MOSFETs are capable of driving either two outputs at 10 A each or one 20-A output, ranging from 2.2 V to 18 V, and 300 kHz to 2 MHz, providing design flexibility.
  • Saves space, component count, and design time by integrating high-side MOSFETs, low-side MOSFETs, drivers, current sensing circuitry, temperature sensing circuitry, and necessary protection functions into a small 6-mm x 6-mm QFN package.
  • The UCD7242's advanced monitoring, including accurate current monitoring outputs (+/-5%) and a temperature monitoring output, reduces part count, increases reliability and speeds time to market.
  • The accurate current limit (+/-3.3%), thermal shutdown, and separate flag per channel protect the power stage system.
  • A dedicated control signal for switching off the low-side MOSFET of each channel makes the UCD7242 highly efficient, even under low load conditions.

Availability and pricing

The UCD7242 is available now in a QFN-32 package and is priced at $2.65 in quantities of 1,000.
