Providing up to 500 mA of continuous current at 0.6-V dc output voltages, the MAX8560, 8561, and 8562 step-down dc-dc converters come in SOT23 and thin DFN packages. Thanks to a 1-mm high, 1-µH inductor and tiny ceramic capacitors, they take up just 19.5 mm2. Prices start at $1.85 each in lots of 1000.
