Toshiba Adds 100V Power MOSFET for Primary Switching of Insulated On-Board DC-DC Converters

Addition to SOP Advance Power MOSFET Family is Targeted for Use in Communication Equipment That Requires Insulated IBC IRVINE, Calif., Aug. 8 // -- Toshiba America Electronic Components, Inc., (TAEC)* today announced a new 100V Power MOSFET, designated TPCA8022-H, for primary switching applications in insulated on-board DC-DC converters and switching regulators. Developed by Toshiba Corp., the device contributes to higher power efficiency and system miniaturization, and is targeted for use in communication infrastructure equipment that requires insulated intermediate bus converters (IBCs). Demand for power supply devices for communication infrastructure equipment has grown due to the spread of high-speed Internet, wireless Internet communication, and Voice over IP. Microprocessors and memory used in such infrastructure equipment must be distributed and multi-staged. As a result, designers have adopted insulated IBC and non-insulated Point of Load (POL) to achieve higher response, higher efficiency, and miniaturization of the equipment while contributing to cost reduction. "This newest member of our SOP Advance family of MOSFETs has been developed to address the needs of communication equipment designers by providing fast switching speed, reduced gate charge, low ON-resistance, a small footprint and excellent power efficiency," said Jay Heinecke, business development director, Discrete Business Unit, for TAEC. The TPCA8022-H is an enhanced, pin-compatible upgrade for Toshiba's earlier TPCA8006-H. It combines Toshiba Ultra-High Speed UMOS-III process technology with SOP Advance low-profile packaging to achieve a high current rating and improve power dissipation. Toshiba SOP Advance packaging is approximately 37 percent thinner than standard SOP-8 and saves space on printed circuit boards. Features o Drain-source withstand voltage (VDSS=100V) suitable for primary switching devices for 48V input bus converters o Realized (low) excellent trade-off between ON-resistance and Qg by adopting ultra high-speed U-MOSIII design o Low drain-source ON-resistance o Low Gate-switch charge o Guaranteed avalanche resistivity characteristics o ZENER DIODE Protection is built-in between Gate and Source o SOP Advance Package contributes to miniaturization of equipment
