MiCOKit uses USB as the power supply and serial communication, and one high efficient DC-DC (TD6817). TD6817 is one monolithic synchronous buck regulator with high efficiency (96%) and constant frequency (1.5MHz). The output voltage has three types: changeable, stable 1.5V and 1.8V. The maximum output current is 2A, while the static loss is just 20uA. The output voltage 2.5V-5.5V is suitable for the power supply of single lithium battery. The switch frequency is set as inner 1.5MHz which is convenient for small SMT inductor and capacitor. It has the function of over-temperature protection.
