Dallas, Tex. – Texas Instruments (TI) has added three power management modules to its SIMPLE SWITCHER family, including the 10-A LMZ31710, which TI said offers the industry’s highest power efficiency in the smallest package at up to 50-percent smaller than similar solutions. The DC/DC power modules drive power-dense applications in a variety of markets including industrial, communications infrastructure, medical, and test and measurement.
These power modules provide a complete power management solution with as few as three external components, delivering a complete solution in a size as small as 195mm2. 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 in a low-profile QFN package that measures 10- x 10- x 4.3 mm.
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 devices are compliant to EN55022 Class B electromagnetic emissions standard for low EMI noise.
TI said "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. The modules also deliver "excellent power dissipation and low thermal impedance of 13.3 degrees C per watt, requiring no de-rating across most input and output voltages."
When used in conjunction with TI's WEBENCH online design tool, the power modules simplify DC/DC conversion and speed the design process.
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.
Availability: The SIMPLE SWITCHER power modules are available in volume now from TI and its authorized distributors. For more information, samples and evaluation modules, visit www.ti.com/lmz31710-pr.
Pricing: The 10-A LMZ31710 is priced at $8.95, the 7-A LMZ31707 is priced at $6.50 and the 4-A LMZ31704 is priced at $5.25, all in quantities of 1,000.
