TI Introduces High-Density Power Solutions for Point-of-Load Design

Texas Instruments Inc. (TI) introduced two new power management integrated circuits for point-of-load designs that raise the bar for size, power density and performance. TI says that its TPS82671 and TPS84620 integrated power solutions ease design and speed time-to-market in portable electronics, communications and industrial applications.

"Point-of-load designs require greater power density, high efficiency and ease of use," said Sami Kiriaki, Senior Vice President of TI’s Power Management business. "These two new power devices achieve new levels of integration and performance, and allow us to support a wide range of customers in portable, telecom, base station and industrial markets like never before."

According to TI, the TPS82671 is the industry’s smallest integrated plug-in power solution at 6.7mm2, providing 90mA per square millimeter. The device combines all external components in TI’s new MicroSiP(TM) package with a 1-mm height – easing design for 600mA portable electronics, such as smartphones. The TPS82671 operates at a very low 17µA quiescent current and achieves power efficiency of greater than 90% from an input voltage of 2.3 to 4.8V. A unique PWM frequency dithering feature reduces noise and improves performance in radio frequency-sensitive designs.

TI’s new 6A, 14.5V TPS84620 achieves a power density of greater than 800 watts per cubic inch with up to 95% efficiency and 30% better thermal dissipation than competitors. The integrated step-down solution combines the inductor and passives onto one device, and requires only three external components, resulting in a complete solution in a space less than 200mm2. The TPS84620 supports a variety of high-power telecom infrastructure and industrial systems that use DSPs and FPGAs.

The TPS82671 comes in an 8-pin, 2.3 x 2.9 x 1mm MicroSiP(TM) BGA package with a suggested resale price of $1.30 in 1,000-unit quantities. The TPS84620 comes in a 15 x 9 x 2.8mm QFN package with a suggested resale price of $7.00 in 1,000-unit quantities.
