TI introduces highest-density 6-A power module

by K C Krishnadas, TechOnline India - December 12, 2011

It simplifies telecom power designs for DSPs and FPGAs by combining the inductor and passives onto one lead frame

Texas Instruments has introduced a new 6-V, 6-A synchronous integrated power module with integrated inductor that achieves 750 watts per cubic inch and peak power efficiency up to 97 percent. The TPS84610 provides thermal performance of 12°C/W and simplifies telecom power designs for DSPs and FPGAs by combining the inductor and passives onto one lead frame, requiring only three external components for a complete, easy-to-design 150-mm2 solution.

The TPS84610 supports input voltages from 2.95 V to 6 V, generates 0.8-V output and has an adjustable switching frequency from 500 kHz - 2 MHz. The 9-mm x 11-mm x 2.8-mm low-noise module meets EN55022 Class B electromagnetic emissions, allowing it to support noise-sensitive applications, such as broadband communications equipment.
Features and benefits 

* Highest power density at 6 A: Delivering 750 W/inch3 power density in a 150-mm2 solution size.
* Simple to design: Only three external components required.
* High performance: Up to nine-percent higher full-load efficiency and 40-percent better thermal performance than competitive solutions.
Expanding power module family

In addition to the TPS84610, TI also introduced four additional power modules with integrated inductors, including the pin-compatible 2-A TPS84210 and 4-A TPS84410, which support input voltages from 2.95 V - 6 V. The 3-A TPS84320 and 6-A TPS84621 modules support input voltages from 4.5 V to 14.5 V and output voltages down to 0.6 V.
TI’s large point-of-load portfolio of voltage regulators and easy-to-use power modules ranges from SIMPLESWITCHER wide-input modules and DC/DC converters to TPS84K integrated power solutions, such as the TPS84610. All are supported by evaluation modules, reference designs and easy-to-use WEBENCH or SwitcherPro design tools.
