High-density power modules

8 February 2012 Power Electronics / Power Management

Texas Instruments has introduced a new 6 V, 6 A synchronous power module with integrated inductor, which achieves 46 W/cm³ and peak power efficiency up to 97%. 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, 150 mm² solution.

The device supports input voltages from 2,95 V to 6 V, generates a low 0,8 V output and has an adjustable switching frequency from 500 kHz to 2 MHz. It 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 2 A TPS84210 and 4 A TPS84410, which support input voltages from 2,95 V to 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 as low as 0,6 V.
