Dont you need to tell us which specific varient of the lm2576 you are using and the input and output voltages ?On a voltage regulator like lm2576t what is the min input current and/or voltage needed to achieve 3amps?
It depends on your load but fig 4 of the datasheet in your link has all the answers.On a voltage regulator like lm2576t what is the min input current and/or voltage needed to achieve 3amps?
LM2576-5.0 (non HV)Dont you need to tell us which specific varient of the lm2576 you are using and the input and output voltages ?
