“Power Good Signal” Function of PC Power SupplyThis article will discuss about the alert function of pc power supply. The main voltage power supply, which supply the computer is +12 volts. Power supply for this circuit should provide a large output current, especially in computers with lots ...
ATX Power Supply PinoutThe ATX power supply generates three main voltage outputs that are: +3.3 V ; +5 V ; and +12 V. Low-power −12 V and +5 VSB (standby) supplies are also generated by this power supply. The −5 V output was ...
12 VDC TO 117 VAC / 60HZ POWER INVERTERCapacitor C5 and potentiometer R12 figure out the frequency of the output signal at pin number 3 of IC1, the 555oscillator. The output signal is differentiated by C3 and C4 before it's input to the base of power transistors Q1 and ...
Bipolar +/- 15V and 5V from Car Battery supplyThis DC to DC Converter use Max 541 from Maxim, IC1 is a switching regulator that generates a 45-kHz signal that drives the gate of MOSFET Q1 BUZ71A from Motorolla. The source of this power supply comes from a 12V car battery voltage. This DC to DC converter have an ...
Computer Power Supply OptionsThe quality of power supply depends not only on power output. Experience shows that if a room is more than one computer and electrical network quality is low (often disappears voltage noise occurs, etc.), systems with powerful power supply systems ...
