Toshiba Launches First DC-DC Converter MOSFETs Using Seventh Generation High Speed Process

February 28, 2010 by Jeff Shepard

Toshiba America Electronic Components, Inc. (TAEC) has launched its latest generation of power MOSFETs for synchronous dc-dc conversion. The seventh generation trench process in the Toshiba fast switching series, UMOS VII-H, enables a significant reduction in gate switch charge and on-state resistance (RDS(ON)) resulting in greater power efficiency.

The first two MOSFETs in the UMOS VII-H series, TPCA8055-H and TPC8055-H, are intended for use in high efficiency dc-dc converter applications in mobile and desktop computers, servers, video game consoles, and other electronic devices, in which they convert input voltage to the level required for various subsystems such as the processor, memory and input-output devices.

In internal testing, the UMOS-VII TPCA8055-H achieved 13% lower R DS(ON) compared to our leading MOSFET from the previous UMOS VI-H generation. The new devices also feature fast switching, enabled through lower gate charge (QSW) and lower gate resistance (Rg).

The TPCA8055-H is offered in low-profile Toshiba SOP Advance surface mount packaging, which measures 5 x 6 x 0.95mm. The other device, TPC8055-H, is offered in industry standard SOP-8 packaging, which measures 5 x 6 x 1.6mm.

"These MOSFETs offer improved parameters compared to our previous generation devices, with high efficiency solutions for synchronous dc-dc conversion in a choice of packages," said Jeff Lo, Business Development Manager, Discrete Power Devices, for TAEC.
