3.5-A step-down DC/DC converters integrate 60-V power MOSFET for high-voltage, space-constrained applications

November 28, 2012 // By Paul Buckley
Texas Instruments Incorporated has introduced two 3.5-A step-down DC/DC converters that claim an integrated MOSFET and industry-leading reference accuracy of one percent.

The SWIFT 60-V TPS54360 and 42-V TPS54340 buck regulators operate over a wide input voltage range and the industry’s widest temperature range for high-performance industrial, consumer, computing, communication and automotive applications. Using these new products together with TI's WEBENCH online design tool can simplify and speed the design process.

The TPS54360 and TPS54340 join TI’s family of Eco-Mode SWIFT DC/DC converters that operate over a wide input range with low operating and shutdown quiescent current. The family also includes the 0.5-A, 42-V TPS54040A and 1.5-A, 60-V TPS54160A that feature precision enable threshold for adjustable under voltage lockout.

Availability and Pricing

The TPS54360 and TPS54340 DC/DC converters are available in volume now from TI and its authorized distributors. Offered in an 8-pin SOIC PowerPAD package, the TPS54360 is priced at $2.10 and the TPS54340 is $1.75 in 1,000-unit quantities. The PowerPAD package lowers the thermal resistance to extend the temperature operation range and improve long-term reliability.
