09:19Power MOSFETs for synchronous DC-DC converters
Toshiba Electronics Europe (TEE) has added two devices to its UMOS V-H Series high-speed switching MOSFETs. The TPCA8012-H and TPCA8019-H n-channel MOSFETs extend the UMOS V- H Series with higher drain current of 40 Amps (A) and 45A (max.) and lower RDSON of 4.9 milliohms (mΩ) and 3.1mΩ , respectively (max. value at VGS = 10V). The UMOS V-H Series MOSFETs are targeted for use in synchronous DC-DC converters in power supplies. The devices join nine other members of the UMOS V-H Series. The TPCA8012-H and TPCA8019-H are offered in SOP Advance packages with a footprint of 5.0mm x 6.0mm. The TPCA8012-H features maximum drain current of 40A, a drain-source voltage maximum rating of 30V and a RDSON of 4.9mΩ (max. value at VGS = 10V). TPCA8019-H is also designed to operate with a 30V drain-source voltage maximum rating, with a maximum drain current of 45A and an RDSON of 3.1mΩ (max. value at VGS = 10V). The SOP Advance package from Toshiba features a 41 percent lower profile than a standard SOP-8 package, and enables approximately 47 percent higher power dissipation. UMOS V is a fifth generation process technology in the Toshiba fast switching series.

09:17Front-end module for WLAN and Bluetooth
Epcos has developed the all-in-one front-end module for Bluetooth and WLAN applications to the 802.11 b/g/n standard. With an insertion height of 1.4 mm, it has a footprint of 4.5 x 3.2 mm² on the circuit board. The module integrates a WLAN power amplifier, a WLAN-Bluetooth switch, a receive balun, and a bias circuit with ESD protection.
In addition, the coexistence filter allows simultaneous operation of WLAN and Bluetooth applications with all mobile phone standards. The LTCC module, with the designation D6101, thus provides all the required functions between WLAN or Bluetooth RF transceivers and the antenna.
