Digital Power & Primarion dual output
Professional design, production and sales of digital integrated circuits mixed-signal semiconductor company Primarion, today announced the launch of dual-output dual-phase PX7522, this product is its programmable digital power conversion and power management integrated circuit products of laptop battery, that PrimarionDi-POL (TM) Series the latest products.
PX7522 is a power conversion and power management ICs can be used for telecommunications, data communications, online services and storage market, synchronous DC / DC converters. PX7522 can regulate two independent outputs, or in a single output mode, adjustable two-phase output. It supports both DCR and RDSon current sensing integrated circuit layout techniques, the output voltage range, in the 0.5V to 8V. This highly configurable control IC utilizes PMBus (TM) and on-chip non-volatile memory (NVM) to enhance its controllability and real-time system monitoring.
Specializing in power electronics market for f4809a , inspiron 6000 battery research and consulting firm, Micro-TechConsultants president MohanMankikar said: “PX7522 launch is Primarion, a growing number of system-level integration trend has taken an important step. PX7522 high degree of flexibility, dual output and system communication PMBus compatibility OEM manufacturers will be to attract attention, they can be cost-effective way to take advantage of this integrated circuit. This is precisely the product process can speed up the pace of digital integrated circuit market applications. ”
PX7522’s control functions utilize digital technology, you can increase the output load under the premise of providing suitable, stable and flexible solution. Primarion on it I2CPMBus integrates industry standard serial interface, so that power supply designer to quickly optimize designs and monitor real-time system performance.
Primarion, vice president of marketing DeepakSavadatti, said: “PX7522 and the Di-POL products to solve the OEM manufacturers are faced with two increasingly important issues, one is the inspiron 600m battery , inspiron e1705 battery marketing time, the other is a simple system-level communication. User only has to use a simple graphical user interface can be around the PX7522 and the Di-POL series of other products quickly and easily build a complete system. designers can use graphical user interface to design, analyze and optimize the entire system, so do not spend a lot of time to do software programming. We are very pleased to be able to provide the market a more comprehensive solution. ”
Users can Primarion’s graphical user interface PX7522 configuration data loaded, edited and saved in the chip non-volatile memory. Configuration data stored on the IC, the controller can follow the designer’s previously configured settings and real-time adjustments to optimize performance accuracy.
Many configurable functions would typically require an external microcontroller to use other technologies to complete. Since fully digital control the kd476 , latitude d600 battery, PMBus interface and user-friendly graphical user interface brings a high degree of flexibility to the user in the current system can be completed PX7522’s power management performance of the optimization.
PX7522 operating voltage of +5 V, switching frequency range 150 kHz to 1 MHz. In the single-output mode, the precise segmentation of each phase output function can enhance its flexibility to support different power requirements of multi-phase output capability. PX7522 can start by detecting and correcting system-level current sense error sources to provide accurate regulation of the internal calibration. Designers can also use programmable current sense temperature compensation to adjust to temperature changes in response to the best accuracy.
Take advantage of this innovative and user-friendly solution, customers can not only save costs, but also can improve system-level performance, Primarion the company will continue to promote the development of digital power management of the powerbook g4 12 battery , powerbook g4 battery, its products can be used for telecommunications, data communications, online services, memory and imaging markets integrated circuits manufacturer.
