The IRU3055CQ is a fixed-frequency five-bit programmable three-phase PWM controller IC with integrated MOSFET drivers. The controller has a 50- to 500-kHz programmable operating frequency, while the output voltage is selectable in 25-mV steps from 1.075 to 1.85V with up to 1.0% output voltage accuracy. Controller is suitable for multiphase buck converters powering CPUs in servers, advanced desktop systems, and motherboards. International Rectifier, www.irf.com. Enter 579

Safety switches

Rope Pull Emergency Stop heavy-duty safety switches are activated by pulling on a cable attached to the switch actuator. The safety switches provide emergency shutdown capabilities for multiple locations by connecting the switches to cables. Safety switches hold their stop contacts open after the cable is pulled and released. Applications include conveyor lines, roll-forming equipment, and robotic work cells.
