IR Introduces Two Configurable Dual Phase PWM Control ICs for High Performance Synchronous Buck DC-DC Converters.EL SEGUNDO El Segundo (ĕl sēgŭn`dō), industrial city (1990 pop. 15,223), Los Angeles co., S Calif., on Santa Monica Bay; inc. 1917. Its products include navigation and computer systems, aircraft parts, office machines, telephone apparatus, and , Calif. -- International Rectifier International Rectifier Corp. (NYSE: IRF) is a manufacturer of power semiconductors (MOSFET, IGBT, diodes and thyristors), located in El Segundo, California, USA. It has a market capitalization of 2.48 billion USD and is listed on the S&P Midcap 400. , IR[R] (NYSE NYSE See: New York Stock Exchange :IRF IRF Interferon Regulatory Factor IRF International Religious Freedom IRF Institut for Rationel Farmakoterapi (German) IRF Inherited Rights Filter (Novell) IRF Inherited Rights Filter ), a world leader in power management technology, today introduced two dual channel synchronous buck control ICs with integrated high performance drivers for medium- to high-current point-of-load (POL) buck converters used in networking, computing, and communications systems. The IR3622MPbF and IR3622AMPbF can be configured to support a single output in current share mode, capable of delivering up to 80 amperes, or to support two independent outputs. The independent channels run 180 degrees out of phase, and reduce the required input capacitance requirement. A significant reduction in output ripple voltage is achieved in single output mode. "These flexible and feature-rich ICs provide greater protection and configurability to meet the design demands of today's high Today's High The intra-day high trading price. Notes: In other words, this is the highest price that a stock traded at during the course of the day. More often than not this is higher than the closing price.

The IR3622MPbF targets 12V single input applications while the IR3622AMPbF can support 5V and 12V applications. Key protection features include selectable hiccup hiccup or hiccough, involuntary spasmodic contraction of the diaphragm followed by a sharp intake of air, which is abruptly stopped by a sudden, involuntary closing of the glottis (opening between the vocal cords); the consequent blocking of air or latched current limit, pre-bias start-up, thermal shutdown protection, and under- and over-voltage protection. The devices feature a programmable switching frequency up to 600 kHz to reduce input and output filtering requirements, and minimizing the size and number of external filter capacitors and inductors needed. Available in a 32-lead MLPQ package, the new ICs also feature two independently programmable soft-start functions to allow system level sequencing of output voltages in various configurations critical for system level start-up. The IR3622 family is well suited to multi-rail applications that require sophisticated power-up and power-down tracking and sequencing of multiple rails by offering a combination of track, sequencing, enable, and "power good" output features that can be used to trigger a sequential rise of output voltages across multiple POL converters. Data sheets for the devices are available on the website at http://www.irf.com/whats-new/nr070712.html. Also, two reference designs are available: the IRDC IRDC Infrared Dark Cloud (astronomy) IRDC International Development Research Center (Canada) IRDC International Race Drivers Club IRDC I Really Don't Care IRDC Intelligence Research & Development Council 3622S for single output (dual phase) and the IRDC3622D for dual output. More information on these reference designs and the associated online simulation tools is available at http://mypower.irf.com. Availability and Pricing The IR3622MPbF, IR3622MTRPbF, IR3622AMPbF and IR3622AMTRPbF devices are available in 10,000-unit quantities at $1.90 USD USD In currencies, this is the abbreviation for the U.S. Dollar.
