[introduction] the crucial challenge that the design personnel that holds facility faces is implementation product is high-powered with low power comsumption. Battery life to holding facility it is very main index, product of power source management must get used to the design requirement of constant change, for example, lower bide one’s time specific power consumption, taller efficiency, ultrathin ply, super- small PCB area, more the control interface that intelligence changes.   DC/DC switch manostat is one of crucial parts in…

[introduction] LDO: LOW DROPOUT VOLTAGE LDO (the abbreviate that is Low Dropout Voltage Regulator, rectifier) low-pressure poor linear manostat, friend name is thought of meaning, for linear manostat, can use only in step-down application. Output voltage to need namely be less than input voltage.   Advantage: Stability is good, load is answered fast. Output ripple is small.   Defect: Efficiency is low, input-output voltage is poor cannot too big. Laden cannot too big, at present the biggest LDO is 5A…

[introduction] what is negative voltage? Respecting voltage, everything is opposite. Different conductance has different potential between body. It is OK that this means a voltage prep above another voltage. This kind of circumstance falls to won’t use “ negaive electricity to press the description of ” commonly. The negative tension that we say is to point to a report to press the ground potential under the system.   What is negative voltage? Respecting voltage, everything is opposite. Different conductance has…

[introduction] long-term since, camera of media player of MP3 player, individual, number and other portable spending kind a challenge that design personnel of application faces is implementation product is high-powered with low power comsumption. These batteries power supply system are used normally embedded digital signal processor (DSP) , when the system handles multimedia application task, DSP can reach capacity of the biggest processing, and when the system is in Morpheus mode, DSP has the smallest power comsumption. Battery life is…
