TI introduces 3-MHz, 2-A DC/DC converters for portable electronics

Tiny, efficient synchronous step-down converters support input voltages of 2.7 V to 6 V
(PresseBox) (Dallas, ) Texas Instruments Incorporated (TI) today introduced two highly efficient 2-A stepdown DC/DC converters for portable electronics applications. The TPS62065 and TPS62067 3-MHz synchronous converters reduces board space and helps extend battery life by providing up to 95 percent power efficiency from a tiny 2mm x 2mm x 0.75mm SON package. For product details, see www.ti.com/tps62065-preu.

The new TPS6206x devices operate from a 2.7-V to 6-V input voltage, allowing them to support lithiumbased batteries with extended voltage ranges or a 3.3-V or 5-V system supply rail. A unique Power Save Mode with excellent PWM to PFM transition allows the converters to operate at light load currents to maintain high efficiency over the entire load range.

Key features and benefits of TPS6206x:

- Smallest size: 3-MHz fixed frequency operation and tiny package size allow support of small inductors and capacitors to achieve a 22 mm2 solution with a maximum height of 1 mm.

- Lowpower operation: Power Save Mode operation at light load currents and 18-µA quiescent current help extend battery life.

- Manages up to 2 A: supports pointofload and processorbased applications, including systems based on TI's TMS320C55x(TM) DSPs.

Availability and pricing

TPS62065 and TPS62067 DC/DC converters come in an 8pin, 2mm x 2mm x 0.75mm SON package, and are available in volume from TI and its authorized distributors with a suggested resale price of $1.40 in 1,000unit quantities. Samples, evaluation modules and application notes are available.
