Conclusion

This application note describes a simple but very useful technique for implementing a

microcontroller controlled low cost non-inverting buck-boost converter. This converter can

be used as a buck converter or as a boost converter or as a buck-boost converter. The

example shows the application of this converter in a battery charger. However it can also be

used in other portable applications or any application getting its power from a rechargeable

battery. Or you could use this technique to make a USB charger to charge Li-ion batteries or

3 or more NiMH Cells in series.
