Friday, May 8th, 2009 at 08:07 | No commentsCategories: Power SupplyShort Content: This article discusses the disk driver designs the new method to involve the voltage regulation, the driver district, the connection, the power source management, the semiconductor processing technology as well as the floppy disk protection and so on many aspects. These methods not only may reduce use these driver's portable expense electronic products power loss, but can also enhance these equipment's durability. Figure 1: Typical lithium ionBattery's working curve. Has the large capacity memory function portable expense electronic products to ... -
Embedded Linux system’s dynamic power source managerial technique
Friday, May 8th, 2009 at 03:07 | No commentsCategories: Power SupplyShort Content: Introduction How to manage the embedded system effectively, particularly mobile termination's power source power loss, is a very valuable topic. The dynamic power source manages DPM (Dynamic Power, Management) the technology provides one kind of operating system rank the power source managed capacity, contains the CPU operating frequency and the voltage, external bus clock rate, aspect and so on external instrumentation clock/power source dynamic regulations, management function. Provide the management function through the user level formulation strategy and the ... -
The liquid-crystal display power source manages circuit design
Thursday, May 7th, 2009 at 22:07 | No commentsCategories: Power SupplyShort Content: 1 introduction Must realize the liquid-crystal display to demonstrate that must have the following 4 units: Controller (Controller), power source management unit (PMU), driving circuit (Driver), liquid crystal display component (LCD). Regarding the resolution small liquid crystal display component, like 128×64, 128×32 and so on modules have controller, the power source management unit, the driver in a body's chip. But regarding the high resolution's liquid-crystal display (for example 320×240, 640×480) needs independent controller, the power source management unit, the ... -
Promotes DC/DC with the ultra thin power inductance switch’s performance
Thursday, May 7th, 2009 at 17:08 | No commentsCategories: Power SupplyShort Content: Increases unceasingly along with the migration of electrons terminal's function, its need's working voltage also becomes along with it diversifies. Looks like the handset, the digital camera, PDA and so on many by the battery power supply product, their LCD back light actuation, the power amplifier module and the IC power circuit needs the different output voltage. Thus, needs DC to come to the DC switch battery supply's voltage to transform the different many voltages to give the above function ... -
High performance, low saturated linear voltage regulator’s development
Thursday, May 7th, 2009 at 12:07 | No commentsCategories: Power SupplyShort Content: In complete machine equipment incessant realization miniaturization and province electrification's today, power loss small low dropout linear voltage regulator (LDO) is becoming the switching power supply to use the linear voltage regulator market the mainstream. In order to realize the high performance and the high velocity, the equipment interior uses the microcomputer or the digital signal processor (DSP) craft is making the progress which and the development year after year progresses by leaps and bounds, at the same time, these ... -

Power source management including power source monitoring, ordering, allowance and so on (Figure 1). The power source management needs the new method. Figure 2 shows Zilker the Labs Corporation's plan.Table 1 power source module BoM comparison The power source module BoM Zilker plan and the simulation plan's comparison see Table 1. As seen in Table 1, the Zilker plan's remarkable merit is: Big electric current ability, ... -
The power source manages some new plan
Wednesday, May 6th, 2009 at 21:07 | No commentsCategories: Power SupplyShort Content: Along with the mobile phone, the notebook, the digital camera, absorb the videocorder, the MP3 broadcast machine and so on portable unit rapidly expand, set a higher request to the power source and the power source management. The electrical power system faces: · the system increases day by day complexity; · needs to manage more voltages, the low voltage as well as the wider input voltage scope; · the system space, the function are getting smaller getting more and more, ... -
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 ... -
Based on TMS320LF2407A modulation direct-current power supply design
Wednesday, May 6th, 2009 at 11:07 | No commentsCategories: Power SupplyShort Content: 1 introduction The modular distributional power source compares the traditional centralism power supply system to have the reliability to be high, the efficiency is high, the volume is small, characteristics and so on easy to operate, but must match reliably by flows the measure to guarantee that the module the electric stress and the thermal load assign evenly. This article proposed that one kind of modular high efficiency direct-current power supply, the single power source module take DSP as a ...
