DFRobot Auto Buck-Boost 3-15V to 5V 600mA - DFR0569 energy monitor Its ultra compact size makesThis power module contains the function of automatic buck boost and integrates with the related circuit of buck boost converter. Its size is just as same as a dime, which is very easy for embedding. Input voltage range 3~15V, fixed output voltage 5V, the maximum load current is 0. 6A and its quiescent current is as low as 200uA. In theory, the work frequency of the module can reach to 1. 2MHz. Besides, it has steady output voltage, which can work long
