10-A SIMPLE SWITCHER® Power Module from TI is Industry's Smallest
DC/DC power modules deliver greater than 95-percent peak efficiency
DALLAS -- Texas Instruments (TI) (NASDAQ: TXN) today introduced three power management modules to its SIMPLE SWITCHER(®) family, including the 10-A LMZ31710, which provides the industry's highest power efficiency in the smallest package, up to 50-percent smaller than similar solutions. The easy-to-use power modules drive power-dense applications in a variety of markets including industrial, communications infrastructure, medical, and test and measurement. Used in conjunction with TI's award-winning WEBENCH® online design tool, the power modules simplify DC/DC conversion and speed the design process.

The 10-A LMZ31710, 7-A LMZ31707 and 4-A LMZ31704 integrated power solutions combine a DC/DC converter with power MOSFETs, a shielded inductor and passives into a low-profile QFN package, providing a complete power management solution with as few as three external components. The modules combine the power efficiency of a synchronous switching regulator at greater than 95 percent with the simplicity of a linear regulator, while eliminating loop compensation design, inductor selection and complex layout placement challenges. Each device is pin-to-pin compatible and features precision enable and soft-start pins, and current sharing for easy scalability from 4 A to 60 A.
The products join TI's portfolio of 50 SIMPLE SWITCHER power modules that include the 3-A LMZ14203 and 2.5-A LMZ35003 for wide-input voltage applications.
LMZ31710/07/04 key features and benefits
-- Complete solution size measures as small as 195 mm(2) with as few as three external components.
-- Achieves greater than 95-percent efficiency with excellent power dissipation and low thermal impedance of 13.3 degrees C per watt, requiring no de-rating across most input and output voltages.
-- Compliant to EN55022 Class B electromagnetic emissions standard for low EMI noise.
-- Very small 10-mm by 10-mm by 4.3-mm QFN package is easy to solder onto a printed circuit board.
