UMOS VI-H MOSFETS for Synchronous DC-DC Conversion Achieve Higher Power Efficiency Through Lower On-state Resistance and Reduced Gate Charge
Developed by Toshiba Corp., the new MOSFETs 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. The six MOSFETs achieve lower (R(DS(ON)) than could be obtained by comparable Toshiba products manufactured with the previous generation process technology. They also feature fast switching, enabled through lower gate charge (Q(SW)) and lower gate resistance (R(g)). The new MOSFETs have Aluminum Strap (Al-Strap) connections instead of conventional wire bond technology to further reduce (R(DS(ON)).
Three of the devices, TPCA8036-H, TPCA8039-H and TPCA8040-H, are offered in low-profile Toshiba SOP Advance surface mount packaging, which measures 5mm x 6mm x 0.95mm. They feature a range of (R(DS(ON)), capacitance and gate charge values, shown in the table below, to meet various load current requirements.
Three similar devices with comparable electrical characteristics, the TPC8036-H, TPC8039-H and TPC8040-H, are offered in industry standard SOP-8 packaging, which measures 5mm x 6mm x 1.6mm.
"These MOSFETs offer high efficiency solutions for synchronous DC-DC conversion with a choice of parameters and packages to meet a diverse range of requirements," said Jeff Lo, business development manager, Discrete Power Devices, for TAEC.
