TI power converter conserves energy in smart meter and sensor designs

High-density SWIFT™ 200-mA, 60-V voltage regulator combines power efficiency, transient protection in tiny 3 mm x 3 mm package

Jun 4, 2012

DALLAS, June 4, 2012 /PRNewswire/ -- Simplifying power design in smart grid and sensor control applications, Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced a 200-mA, 60-V SWIFT high-density, synchronous step-down regulator with 90-percent high efficiency and low noise performance. With a solution size of only 125 mm2, the TPS54061 integrates both high side and low side power MOSFETs, and improves efficiency in industrial automation and 4-mA to 20-mA sensor control applications, as well as smart meter, Power over Ethernet, computing and consumer designs. For samples, WEBENCH® design tool and evaluation module visit: www.ti.com/tps54061-pr.

The TPS54061 converter manages input voltages from 4.7 V to 60 V, and can withstand high-voltage transients up to 62 V, while saving energy – even under light load conditions. The converter supports various TI processors, including Stellaris® ARM® Cortex™-M MCUs, C5000™ DSPs and ultra-low power MSP430™ 16-bit MCUs.

Key features and benefits of the TPS54061:

  • High efficiency and light-load performance: 62-V transient protection for specification overhead; 90-percent efficiency at 24 Vin, 5 Vout at 50 kHz.
  • Low-power operation: 90-uA operating current with a shutdown current of only 1.4 uA.
  • Smallest solution size: Synchronized switching frequency up to 1.1-MHz and small SON package with integrated diode, high and low-side FETs result in a 20 mm2 board space savings compared to competitive products.

Availability and pricing

The TPS54061 is available in volume now from TI and authorized distributors in a 3-mm x 3-mm SON PowerPad™ package. Suggested resale pricing is $1.65 in 1,000-unit quantities. The TPS54061EVM-142 evaluation module (EVM) operates from an 8-V to 60-V input (24-V nominal) and provides a 3.3-V output at 200mA.
