Zener Diode VS voltage divider VS DCDC converter VS voltage regulater
Hello
When a person wishes to convert from one voltage to another (say for example DC 12v to 9v) several things come to his\her mind , whether to use voltage divider circuit, zener diode circuit, IC voltage regulater circuit or DC\Dc converter ?
Dear crazyengineers what do you think each circuit advantage over the other ? most cases shows that people would go for IC voltage regulater
In my modest experience,
Voltage divider wont be sufficient because the voltage output fluctuate when Ps changes , plus Resistors will require high values and will dissipate alot of heat (loss of unwanted energy) and will draw alot of current from power source which will weaken the battery lifecycle
Zener diode, is temperature sensitive which will effect its voltage regulation, plus it draws 0.6v from the power supply to operate and that will cause some certain voltage drop
Voltage regulater IC are two types , one is linear another is switch regulater
i never used switch regulater and have no idea about it
considering linear regulater it contains the two previous circuits in the chip, plus it has a temperature switch in order to switch it off when it exceeds its temperature limit, while a heat-sink will be recommended to use to cool down the voltage regulater, in order it operates for longer period
DCDC converter can have the advantage that some has the option of having galvanic separation in it, it is able to connect two circuits together which functions in different polarities without one circuit affecting the other circuit in means of causing noize
Crazyengineers correct me if i had made a mistake up there and add what you know guys , and to make it clear, my question what makes each circuit applicable for certain applications , what advantages one on another
big ups

Harshad ItaliyaGood Information ! -
gargoorgodfather :
thank you for passing by, though i would had been happier if you've replied me with extra info which you may had obtained during your practical approach or maybe also theoretical because the info i gave is weak , need more details -
d_vipulhey gargoor,
please give more explanation for DC-DC converters..........
by d way mostly VOLTAGE REGULATORS are used to keep the fixed voltage across the equipment..........
as for voltages upto 10V IC's with voltage dropof 0.1V are available......
and for voltages upto 25V IC'S with voltage drop of 0.5 are available..........
and for voltages above 25V, DC-DC Converters or Choppers are used due to their higher efficiency..............
Regards,
VIPUL
