Linear Technology Corp. introduces the LTC3870, a dual phase synchronous step-down slave controller that can generate currents up to 240 A when paired with a companion master controller by extending the phase count in multiphase applications. Compatible master controllers include the LTC3880 and LTC3883 digital power system management controllers.
Flip chip is a type of surface mountable packaging technology that reduces footprint and thickness (compared to conventional packaging), weighs less, is easy to assemble, lowers production costs and improves electrical and thermal performance. Their significant size and weight reduction makes them ideal for use in a variety of mobile devices.
RFMW Ltd. announces application and sales support for the Telemakus TEP2000-4 digital phase shifter. This laboratory quality phase shifter has a minimum phase range of 360 degrees with 12-bit, 0.25 degree resolution and operates over the bandwidth of 1 to 2 GHz. Maximum RF input for linear operation is +6 dBm but the device can handle up to +20 dBm.
The NI PXIe-7975R FPGA module features a digital signal processing (DSP)-focused Xilinx Kintex-7 FPGA and 2 GB/s of onboard DDR3 DRAM. This FPGA incorporates 1,540 DSP slices, which you can use to implement digital filters, custom signal processing, and Fast Fourier Transform (FFT) logic, all of which are commonly found on analog FPGA-based instruments.
Linear Technology Corp. announces the LT3840, a wide range synchronous step-down DC/DC controller which includes a 7.5 V buck-boost bias voltage to provide efficient gate drive over a 2.5 to 60 V input voltage range. The LT3840 generates a 7.5 V bias voltage for MOSFET gate drive regardless of whether the input voltage is above, below or equal to 7.5 V.
Linear Technology Corp. announces the LTC3784, a high power two phase single output synchronous step-up DC/DC controller that replaces rectifying boost diodes with high efficiency N-channel MOSFETs.
