Electronic Circuit Schematic Switching Power Supply 0-25V, 10 A using L4970A

Robometricschool. - There are many electronic circuit schematic of switching power supply that will help you to build power supply to supply you electronic devices now. One of electronic circuit schematic of switching power supply that will help you to produce 0 to 25 volt with 10 ampere is Electronic Circuit Schematic Switching Power Supply 0-25V, 10 A using L4970A.

In here we will show you Electronic Circuit Schematic Switching Power Supply 0-25V, 10 A using L4970A like in figure 1 below.

Component List
  1. The main component in figure 1 is IC L970A
  2. Others component you can see more like in figure 1 above

Description

Electronic circuit schematic like in figure 1 above is Electronic Circuit Schematic Switching Power Supply 0-25V, 10 A using L4970A. To know more about the description of the circuit schematic, please follow description below:
  1. The switching power supply circuit has a variable output voltage from 0 VDC to 25 VDC supply with a maximum current capability is 10 Amperes.
  2. The switching power supply circuit constructed with the main components of IC L4970A. L4970 IC is an IC chip step-down voltage regulator positive switching regulator with power DMOSFET which has been integrated in the L4970 IC chip.
  3. Circuit schematic of switching on the power supply above can provide an output voltage of 0 - 25V adjustable by means of potentiometer VR determine the position of the lever 18 is connected to the IC KOhm L4970A. At the output of the switching regulator power supply network with the IC L4970 over there turns 150 UH. Circumference of 150 UH is made ​​using a 1.3 mm wire size email and wound 45 turns on the iron core.
  4. Switching power supply circuit above using a step-down transformer from 220VAC to 28 VAC. Then the AC voltage from the transformer changed form the proficiency level DC voltage using a diode bridge and capacitor electrolyte (Elco) 3300UF. 
  5. IC L4970 functions as a voltage regulator with a switching system that completed with DMOSFET in power regulator IC. IC L4970 will generate heat during operation, so it needs to be equipped with cooling (heat sink) to create the heat generated by the IC L4970. (Source:skemarangkaianpcb blog)
