TI Power Converter Conserves Energy in Smart Meter and Sensor Designs

June 04, 2012 by Jeff Shepard

Texas Instruments Inc. (TI) introduced a 200mA, 60V SWIFT high-density, synchronous step-down regulator with 90-percent high efficiency and low noise performance. With a solution size of only 125mm2, the TPS54061 integrates both high side and low side power MOSFETs, and improves efficiency in industrial automation and 4 to 20mA sensor control applications, as well as smart meter, Power over Ethernet, computing and consumer designs.

The TPS54061 converter manages input voltages from 4.7 to 60V, and can withstand high-voltage transients up to 62V, 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: 62V transient protection for specification overhead; 90-percent efficiency at 24 Vin, 5Vout at 50 kHz.

-- Low-power operation: 90µA operating current with a shutdown current of only 1.4µA.

-- 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.

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