Lengthens the battery service life using the dual processor
Wednesday, October 7th, 2009 at 09:24 | No commentsCategories: DSPShort Content: Turns toward a lower power loss, the high performance battery to supply the electrical form system development the tendency to be without a doubt. Speaking of the battery supply, the consumer hoped that the portable electronic products can by "the lower electric quantity execution multi-purpose", simultaneously, the numerous manufactured products also start to transfer use the battery power supply. Digital signal processor (DSP) commonly used in request high performance application domain, thus causes the clock running rate to promote unceasingly. ... -
Based on MSP430 monolithic integrated circuit’s switch voltage-stabilized source design
Tuesday, May 26th, 2009 at 22:39 | No commentsCategories: SCMShort Content: 1 introduction The MSP430 series monolithic integrated circuit is the new generation 16 monolithic integrated circuits which American TI Corporation produces, is one kind of ultra low power loss composite signal processor (MixedSignal Processor), it has the low voltage, the ultra low power loss, formidable handling ability, the system work stable, rich internal merits and so on peripheral device, convenience development, has the very high performance-to-price ratio, in domains and so on engineering control has the extremely widespread application ... -
Uses in the domestic electric appliances, the controller and alternating current supply’s coordination type circuit protection
Wednesday, May 6th, 2009 at 16:07 | No commentsCategories: Power SupplyShort Content: The overflow which, the overheated coordination preservation technology (PPTC) realizes with the high polymer positive temperature coefficient component may protect in domestic electric appliances' electric motor, the controller and the electronic component. The PPTC component's resistance is small, the size and the fuse are the same, when presents the breakdown, will limit the dangerous the big electric current to wind through. However, after fixing the breakdown, and dump, the PPTC component can regain the original low resistance condition, it protects ... -
Realizes in the telecommunication system inserts hotly pulls out power source’s design method
Monday, May 4th, 2009 at 14:07 | No commentsCategories: Power SupplyShort Content: Now the most important system cannot tolerate has any dawdle machine, we forever do not hope the telephone switchboard, the data net equipment, the honeycomb means of communication or dawdles machine and so on hospital information system. But even if has the redundant data way, the power source and the memory most reliable system, also occasionally will still break down. For example, it possibly by the component breakdown as well as by cannot forecast the event (for example thunder ... -
The FA5310 switching power supply controls IC and the application
Sunday, May 3rd, 2009 at 23:07 | No commentsCategories: Power SupplyShort Content: The abstract introduced the FA5310 switching power supply controls IC the performance, the characteristic and the principle of work, and gave its one kind to apply the electric circuit specifically. -
High energy efficiency ATX power source solution
Sunday, April 26th, 2009 at 12:00 | No commentsCategories: Power SupplyShort Content: The personal computer (PC) application is getting more and more widespread, it is also getting bigger and bigger to the electrical energy consumption. Speaking of the desktop computer, what usually use is the ATX power source. The typical ATX power source has used the tradition to stir up the topology in the past (1 or 2 switches), its energy efficiency about 70%. In recent years, along with energy conservation environmental protection pressure's enlargement, enhanced the ATX power source energy ... -
The high efficiency bit - 48V inserts hotly pulls out the controller design
Saturday, April 25th, 2009 at 06:00 | No commentsCategories: Power SupplyShort Content: Many large-scale telecommunications and the data communication systems use insert on common back board many circuit wafers or the bit construct to the rack. The back board as well as between them the correspondence provides the power source for the bit (e.g. - 48V, 12V). Because the back board power source is at the opening condition throughout, therefore is called "hot" or "is moving" the back board. The bit must insert the rack, but cannot affect on the ... -
Stratix FPGA power source project design and confirmation
Thursday, April 23rd, 2009 at 19:00 | No commentsCategories: Power SupplyShort Content: In view of Stratix the series FPGA system power source demand situation, has given a set based on the Intersil highly effective three output synchronization compensation stabler "monolithic" the power source solution. According to the empirical datum analysis and the confirmation, this plan has the strong feasibility, and in aspects and so on power loss, efficiency and stability surpasses the tradition "the multi-pieces" the power source plan. Stratix series FPGA is Altera Corporation promotes face the high ... -
Based on DSP high frequency three-phase high efficiency power source design
Thursday, April 23rd, 2009 at 14:00 | No commentsCategories: Power SupplyShort Content: Along with national defense science and technology's development and astronautics enterprise's need, the flight vehicle attitude control as well as the vibration experiment's demand increases gradually. In the ground build analog simulation platform, is astronautics area research convention. He may reduce the fund economically the inputs, increases the duplication and the observability from the experimental study. This article introduces based on the DSP three-phase high efficiency high accuracy high frequency power source is in the simulation research the essential core ... -
Multimedia handset’s power source management plans
Thursday, April 23rd, 2009 at 03:59 | No commentsCategories: Power SupplyShort Content: The handset television, the handset game as well as the audio frequency broadcast and so on multimedia applications presented the huge challenge to handset's in power source management design. The handset designers need while to join the new multimedia function, maintains the handset exquisite contour and maintains battery's long life. Has provided the splendid new function newly using the processor, but the price is the power loss is higher. The new AV function means that music playbacking time is longer, ...
