    i got a project to be done with battery charging with 3A using lm350 ....... and also i need show the circuit in simulation how can i get it done in simulation (multisim,ckt maker)

    Here is a simple circuit using IC LM 350, which can be used for charging 12V lead acid batteries. This circuit is perfect for “constant charging” 12V lead acid batteries. The circuit is designed as a constant voltage source with a negative temperature coefficient. The transistor Q1 (BD 140) is used as the temperature sensor. The transistor Q2 is used to prevent the battery from discharging through R1 when the mains power is not available. The circuit is designed based on the voltage regulator IC LM350.The output voltage of the charger can be adjusted between 13-15 V by varying the POT R6....want to know more search in Google.
