In daily life, people is more and more serious to the dependence of electronic equipment, of electronic technology change, also mean people to express great expectations to the technical development of power source at the same time, technical ultimate cluster manages for everybody introduction power source below. For the parts of an apparatus or appliance that semiconductor of power source management includes from place, emphasize integrated circuit of power source management clearly (IC of power source management, chip of abbreviation report source control) the position and action. Semiconductor of power source management includes two shares, namely integrated circuit of power source management and semiconductor device of type of schism of power source management. Integrated circuit of power source management includes a lot of sort to fasten, divide into voltage to adjust again roughly with interface circuit two respects. Voltage wither is whole implement include linear low pressure to fall manostat (namely LOD) , and, circuit of negative output series, do not have wide modulation of arteries and veins in addition (PWM) model switch circuit. Because the technology progresses, the physical size of circuit of the number inside integrated circuit chip is smaller and smaller, consequently working power source develops to low voltage, emerge as the times require of a series of new-style voltage regulator. Power source management basically has transistor of effect of field of interface driver, motor driver, power with interface circuit (MOSFET) driver and tall voltage / the indication driver of big electric current is waited a moment. Semiconductor device of type of schism of power source management includes the power semiconductor device of a few traditions, can be its cent two kinds big, one kind includes rectifier and; of brilliant brake canal another kind is dynatron model, include power bipolar transistor, the transistor of power field effect that contains MOS structure (MOSFET) with insulation bar ambipolar model transistor (IGBT) wait. Going up somehow for, run a large number of development of IC because of power source just about, power semiconductor just changes call semiconductor of power source management. Also be the integrated circuit because of so much (IC) enter power source field, people just comes morely with power source management the power source skill that address shows level. Semiconductor of power source management this medium dominant part is IC of power source management, roughly but reduce is undermentioned 8 kinds. 1, AC/DC modulation IC. Embedded low voltage controls circuit and high-pressured switch transistor. 2, DC/DC modulation IC. Include step up / step-down adjuster, and charge pump. 3, preliminary adjustments of PFC of power factor control makes IC. Carry sacrificial vessel have rendered great service to lead factor the power source input of corrective function. 4, pulse modulation or arteries and veins modulation PWM/ PFM controls IC. Mix for pulse frequency modulation / or controller of pulse width modulation, use at drive exterior switch. 5, linear modulation IC (if linear low pressure falls manostat LDO) . Include to and negative to adjuster, and low pressure falls LDO modulation canal. 6, batteries charges and manage IC. Include batteries to charge, protection and n show IC, and can have batteries data news report " intelligence " batteries IC. 7, hot flashboard controls IC (absolve be inserted from inside working system or pull out the influence of another interface) . 8, the switch function Ic of MOSFET or IGBT. In IC of these power source management, voltage adjustment IC is to expand the one part with the fastest, the largest crop. IC of all sorts of power source management basically are mixed a few relevant application are contacted, be aimed at different applying so, return the parts of an apparatus of OK and listed more type. The technical trend of power source management is tall efficiency, low power comsumption, intelligence change. Raise efficiency to involve the content of two different respects: Want to carry the overall efficiency that energy changes on one hand, the dimension; that still hopes to reduce facility at the same time is protection on the other hand dimension is changeless, improve efficiency substantially. Communicating / dc (AC/DC) in commutation, low on-state resistance, the need of more efficient adapter and power source in according with the computer and telecommunication application. The respect is designed in power source circuit, wait for functional bad news to had fallen commonly 1W is the following, can improve power source efficiency to 90% above. Should reduce further remain now functional bad news, need to have new IC workmanship technology and the breakthrough that design a respect in circuit of low power comsumption. CNC Milling
