Texas Instruments has introduced two 3.5-A step-down DC-DC converters with an integrated MOSFET and industry-leading reference accuracy of 1%. The 60-V TPS54360 and 42-V TPS54340 buck regulators operate over wide input-voltage and temperature ranges 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 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 thresholds 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 to 42 V (TPS54340)
- Robust input-voltage protection.
- Current-mode control allows simple external compensation and flexible component selection.
- Integrated 92-m? high-side MOSFET provides high efficiency at high currents.
- 1% reference accuracy from ?40 to 150 °C better regulates output voltages over all operating conditions.
- Low-dropout operating mode approaching 100% duty cycle minimizes input to output voltage drop.
Availability, packaging and pricing
The TPS54360 and TPS54340 DC-DC converters are available in volume now. 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 operating temperature range and improve long-term reliability.
