#106250 - Simple Switchers LM2575 Responding to: ???'s previous message |
Dear Nikhil,
for saving battery you can use Swithcers. They are very efficient efficiency in the range of 80%. They will heat lesser give more current without heatsinks and will save batteryt too. Designing power supply with LM2575 switchers is simplest in my opinion. All you need is a schottkey diode two caps and an inductor. Recommended layout and component value selection guides are given in datasheet. For my products earlier i used LM323 linear regulators but now i have started using LM2575 they run cooler and save energy too. Regards, Prahlad Purohit |
