TI introduces 2.5A, 60V Step-Down SWIFT DC-DC Converter
Texas Instruments Inc. (TI) introduced its first 2.5A step-down SWIFT™ converter to support input voltages up to 60V. The new TPS54260 monolithic synchronous switcher with integrated high-side FET provides up to 95% efficiency and low operating current to 12-, 24- and 48V point-of-load designs and GSM/GPRS modules used in electronic meters (e-meters), fleet management and security systems.
According to TI, 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 138µA. When disabled, the device draws only 1.3µA.
Additional features and benefits of the TPS54260 include: integrated 200mΩ high-side FET supports a 2.5A continuous current, and a power stage input voltage range from 3.5 to 60V; wide switching frequency range (100 kHz to 2.5 MHz) combines efficiency with design flexibility, and comes in a space-saving, thermally enhanced 3 x 4.9 x 1mm monolithic MSOP package that minimizes footprint; synchronized switching frequency from a master clock eliminates beat noise in sensitive data acquisition circuitry; and feature-rich IC includes power-good, enable and tracking pins for sequencing.
The TPS54260 is available in volume now in a 3 x 4. mm MSOP PowerPad™ package. Suggested resale pricing is $2.30 in 1,000-unit quantities.
