Circuit Schematic 12V LDO Solar Charge Controller using MOSFET

Eltronicschool. - Still discuss about solar charger circuit schematic. After we give you Top Solar Battery Charger Circuit Schematic using LM317T, now we will continue to show you one again solar charger circuit schematic. This is Circuit Schematic 12V LDO Solar Charge Controller using MOSFET like in figure 1 below.

Description

Circuit schematic like in figure 1 above is Circuit Schematic 12V LDO Solar Charge Controller using MOSFET. This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator –their compatibility seems like a marriage made in heaven. Voltage output is adjustable. It is mainly intended for charging 12V lead-acid batteries.


  1. Solar panel rating: 50W (4A, 12V nominal) (open circuit voltage: 18 to 20V)
  2. Output voltage range: 7 to 14V (adjustable) (not recommended for 6V applications)
  3. Max power dissipation: 16W (includes power dissipation of D3)
  4. Typical dropout voltage: 1.25V @ 4A
  5. Maximum current: 4A (current limiting provided by solar panel characteristics)
  6. Voltage regulation: 10mV (no load to full load)
  7. Battery discharge: 1mA (Chinese controls discharge at typically 5mA)
  8. LED indicators:
  9. RED: Solar panel active
  10. GREEN: Series regulator limiting current (fully charged or topping off)
  11. Reverse battery protection: Control shuts down if battery is inadvertently connected reverse.
