  Add flash-disc function to non-USB products 7/3/2007

  6th March 2007 – FTDI (Future Technology Devices International) has recently added a USB flash disc interface module to its range: you can use the VDRIVE2 to add a flash disc feature to industrial ....

  LCD controller packaged for portable products 1/3/2007

  27th February 2007 – EM6111 is a low multiplex controller and driver for monochrome TN and STN LCD displays, from EM Microelectronic, that operates on a wide supply voltage, ranging from ....

  High-voltage buck switching regulator handles 100V 1/3/2007

  27th February 2007 – National Semiconductor has extended its recently-introduced architecture of “emulated current mode*” buck voltage regulators to span up to 100V, which the company says is an industry ....

  Analog divider uses few components 1/3/2007

  Although microprocessors may offer calculations of greater precision, there's still room for analog- computation techniques in a designer's circuit collection. As an example, the analog-divider circuit in Figure 1 offers reasonably good accuracy ....

  Simple circuit allows long PWM soft starts 1/3/2007

  Available from multiple sources, the UC384X family of currentmode, PWM (pulse-width-modulated) power-supply controllers offers good performance and has generated a variety of similar ICs. All members of the UC384X family and its variants share ....

  Hall-effect current sensor covers 5 to 70A for motor controls and drives 1/3/2007

  Designers may best know the range of LEM's current sensors for operation at higher power levels such as those you might encounter in large motor drives or inverters. Now, the company has introduced Minisens, an SO-8-packaged, ASIC-based transducer ....

  NATIONAL ADDS SIX SIMPLE SWITCHERS 1/3/2007

  If you thought that power-conversion designers could not possibly come up with yet another conversion architecture - wrong. National Semiconductor has added six high-frequency buck regulators to its Simple Switcher product family, employing a ....

  Designing instrumentation circuitry with rms/dc converters - Part I 1/3/2007

  Using rms to measure waveforms furnishes the most accurate amplitude information (Reference 1). Rectify-and-average schemes, which you usually calibrate to a sine wave, are accurate for only one waveshape, however. Departures ....
