During inefficiency of linear voltage regulators, switching regulators are in no doubt fairly better choice, at least to step down higher voltage and used as an input voltage to standard linear regulators (avoiding ripple issue with MCU usage).
I have tried old, widely used MC34063 and it is fine except it require too many additional components, as well as very low resistor values not commonly available, which extends complexity of the circuit adding many commonly available in parallel...
As there is many of switching regulators around, I'm interested in experience of other members with other switching regulators, require non (labeled for standard values as 3.3 or 5V, if exists) or just few necessary components allowing input up to 20V and produce output for low power circuits around MCUs, which not exceed 250mA.
Thanks.
