lm2575
Hi friends.
I have made a 12V to 5V dc-dc converter using LM2575. As the datasheet says it is a 1A step down Buck regulator. In my circuit the load's current is about 980 mA and the efficiency of the regulator is about 80 %. Nonetheless the dissipated power emerging as heat in the regulator (which is mount on a suitable heatsink)
seems to be much and harmful to my circuit.
Now I want to know if there is or not any other device to use instead of LM2575-5 to decrease the produced heat ? or may I use any other topology for this purpose?
I will be really grateful to any help.
