STMicroelectronics' latest digital power amplifier, the STA510F, can drive up to 100W per channel of audio into stereo 8-ohm loads. The device will also drive 4 x 50W into 4 ohms, or up to 200W in a mono configuration, using STM's proprietary full flexible amplification method of digital modulation. However, it still accepts signals from other drivers using any PWM modulation scheme such as ternary, phase shift, or binary.
OnChip Devices introduced low capacitance ESD protection devices for single and dual USB ports. These devices protect the two data lines and the power rail of the USB 2.0 high speed interface. The ESD2100-02 and ESD2100-04 (2 and 4 channels, respectively) have a sub-1pF line capacitance to ensure minimal distortion USB signal, offering a compromise between low line-to-ground
Schaffner EMC extended its FN9222 inlet filter series to include the new FN9222E, which as an earth line choke for designs needing greater attenuation performance. The FN9222E outperforms Schaffner's existing IEC inlet filters and is mechanically compatible with the panel cut-outs of traditional filters. Each filter has a traditional screw mounting.
TT Electronics IRC released the PAT3060P high-power attenuator and RFTF surface-mount transmission line terminator, both featuring low VSWRs at high frequencies. They are useful for RF power meters, RF and microwave power amplifiers, radar, satellites, avionics, wireless communications, RF power sources, and microwave test instruments. The PAT3060P's frequency has a VSWR of less than 1.3 at 10 GHz. Attenuation values include 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 16 and 20 dB.
STMicroelectronics announced a flexible controller for high-performance flyback power converters, which can operate in fixed-frequency (FF) or quasi-resonant (QR) mode. The chip integrates protection capabilities commonly implemented with external components, and is useful for applications such as AC/DC adapters/chargers, monitors, DVD players, and set-top boxes. During light load, the chip enters a controlled burst state at low frequency with constant peak current
Everlight’s announced the 5W EHP-B03 Series emitters which are designed, binned and tested for standard operation at 700 mA and have the capability of being driven at 1000 mA. The series come with a special Star design – MCPCB (DLC based), which allows effective heat dissipation and low thermal resistance between junction and Star to a typical value of 11K/W. They deliver light output performance of 250 lm at 700 mA
Fairchild Semiconductor's FAN7316 and FAN7317 are CCFL backlight inverter drive ICs for N-N half-bridge, push-pull, and P-N full-bridge LCD designs. A wide input voltage range, built-in open lamp protection, and open lamp regulation eliminate up to 30 external components in traditional four-lamp circuit inverter designs. The FAN7316 runs on 4.5V to 24V, and the FAN7317 uses 6V to 25.5V. Other features are
Semtech announced the SC198 and SC198A, two new dual-output synchronous DC/DC buck converters each with eight VID programmable output voltage settings that allow portable systems manufacturers to lower processor voltages and extend the battery life of their devices. The converters are suited for use in
Phoenix Contact announced three additions to its Inline Modular family of products: two bus couplers and a backplane expansion module. The Modbus TCP/UDP bus coupler offers the same functionality as the company's Inline Modular Ethernet Bus Coupler in a compact form. The new product incorporates
National Instruments announced its first USB-controlled RMS RF power meter, measuring just 8.5" × 1.18" × 2.2". The 6 GHz NI USB-5680 is powered solely from a USB cable and consumes only 100 mA. It has a frequency range of 50 MHz to 6 GHz, dynamic range of 63 dB, and amplitude accuracy of ±0.18 dB. An executable soft front panel and software libraries are
Emerson Network Power debuted two high-efficiency external AC/DC power adapters, models Astec AD50 and AD100.
