TI introduces 2.5-A, 60-V step-down SWIFT(TM) DC/DC converter

DALLAS, May 3 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) introduced its first 2.5-A step-down SWIFT™ converter to support input voltages up to 60 volts. The new TPS54260 monolithic synchronous switcher with integrated high-side FET provides up to 95 percent efficiency and low operating current to 12-, 24- and 48-V point-of-load designs and GSM/GPRS modules used in electronic meters (e-meters), fleet management and security systems. For samples and evaluation modules visit: www.ti.com/tps54260-pr.  

The TPS54260 offers a high degree of performance and reliability, including current mode control, which provides fast transient response, simple external compensation and flexible component selection. The device also enters into a low ripple pulse skip mode, which reduces the no load, regulated output supply current down to 138 uA. When disabled, the device draws only 1.3 uA.

Additional features and benefits of the TPS54260

• TI's high-efficiency SWIFT device with integrated 200-milliohm high-side FET supports a 2.5-A continuous current, and a power stage input voltage range from 3.5 V to 60 V.
• Wide switching frequency range (100 kHz to 2.5 MHz) combines efficiency with design flexibility, and comes in a space-saving, thermally enhanced 3 mm x 4.9 mm x 1 mm monolithic MSOP package that minimizes footprint.
• Synchronized switching frequency from a master clock eliminates beat noise in sensitive data acquisition circuitry.
• Feature-rich IC includes power-good, enable and tracking pins for sequencing.

Availability and pricing

The TPS54260 is available in volume now from TI and its authorized distributors in a 3 mm x 4.9 mm MSOP PowerPad™ package. Suggested resale pricing is $2.30 in 1,000-unit quantities.

Managing the system power requirements

In addition to the TPS54260, TI SWIFT converters efficiently manage the system power requirements in industrial applications that use TI microcontrollers (MCUs) including C2000™ real-time control MCUs and MSP430™ ultra-low power MCUs. Other 60-V converters, such as the TPS54160 1.5-A device and TPS54060 0.5-A device, provide lower current and high-efficiency. All three SWIFT converters are pin-compatible for design flexibility.
