DC/DC Buck Regulators deliver tight reference accuracy.
December 20, 2012 -
Supplied in 8-pin SOIC PowerPAD™ package, SWIFT™ TPS54360 (60 V) and TPS54340 (42 V) buck regulators have respective input ranges of 4.5–60 V and 4.5–42 V. These 3.5 A step-down DC/DC converters, which integrate 92 mΩ high-side MOSFET, offer 1% reference accuracy from -40 to +150°C for optimal output voltage regulation over all operating conditions. Current mode control allows external compensation and flexible component selection, and low dropout operating mode approaches 100% duty cycle.

DC/DC converters integrate 60-V power MOSFET for high-voltage, space-constrained applications
DALLAS – Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced two 3.5-A step-down DC/DC converters with 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. For more information and samples, visit www.ti.com/pmp-tps54360-pr-en. Watch a video demonstration at www.ti.com/pmp-tps54360-prv-en.
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 1.5A, 60-V TPS54160A that feature precision enable threshold for adjustable under voltage lockout.

Key features and benefits of the TPS54360 and TPS54340 DC/DC converters
• Wide input range from 4.5 V to 60 V (TPS54360) or 42 V (TPS54340) offers robust input voltage protection.
• Current mode control allows simple external compensation and flexible component selection.
• Integrated 92-mOhm high-side MOSFET provides high efficiency at high currents.
• Industry-leading one-percent reference accuracy from -40°C to 150°C better regulates output voltages over all operating conditions.
• Low dropout operating mode approaching 100 percent duty cycle minimizes input to output voltage drop.
Availability, packaging 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 US$2.10 and the TPS54340 is US$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.
