Power MOSFETs suit synchronous DC-DC converter applications.

Press Release Summary:



Part of UMOS VII-H Series, Models TPCA8055-H and TPC8055-H enable reduction in gate switch charge and on-state resistance for optimal power efficiency. Units convert input voltage to level required for various subsystems such as processor, memory, and input-output devices. Housed in 5 x 6 x 0.95 mm SOP Advance package, Model TPCA8055-H features max RDS(ON) of 2.5 at VGS=4.5 V, while Model TPC8055-H, housed in 5 x 6 x 1.6 mm SOP-8 package, features max RDS(ON) of 2.5 at VGS=4.5 V.

First DC-DC Converter MOSFETs Using Toshiba Seventh Generation High Speed Process Achieve Lower Resistance and Gate Charge



UMOS VII-H MOSFETS for Synchronous DC-DC Conversion Achieve Higher Power Efficiency

IRVINE, Calif., -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, has launched its latest generation 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.

Developed by Toshiba Corp., 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, videogame consoles, and other electronic devices. 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 percent(1) lower RDS(ON) compared to the leading Toshiba 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-His offered in low-profile Toshiba SOP Advance surface mount packaging, which measures 5mm x 6mm x 0.95mm. The other device, TPC8055-H, is offered in industry standard SOP-8 packaging, which measures 5mm x 6mm 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.
