Texas Instruments Inc. debuts the TPS84610, a 6V, 6A synchronous integrated power module with integrated inductor, which claims an industry-best power density of 45.767mW/mm3 (750W/inch3) and peak power efficiency up to 97 per cent.

The TPS84610 touts excellent thermal performance of 12°C/W, which is 40 per cent better than competing modules. The device 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 150mm2 solution, according to TI.

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

In addition to the TPS84610, TI also introduced four additional power modules with integrated inductors, including the pin-compatible 2A TPS84210 and 4A TPS84410, which support input voltages from 2.95V to 6V. The 3A TPS84320 and 6A TPS84621 modules support input voltages from 4.5V to 14.5V and output voltages down to as low as 0.6V.

All devices are supported by evaluation modules, reference designs and easy-to-use WEBENCH or SwitcherPro design tools.

The TPS84610 is available in volume now from TI and its authorised distributors in a 9mm x 1mm x 2.8mm QFN package. Suggested resale pricing is Rs.291.48 ($6.50) in 1,000-unit quantities.
