DC-DC Automatic Step Up-down Power Module (3~15V to 5V 600mA)

Introduction This 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 time without voltage shift. The maximum conversion can reach to 85%. So it is suitable for the occasions with high requirements. You can use this power module to DIY mobile power pack and provide constant power for your projects. Applications Power supply for controller main-board, DIY current source, floodlight, DIY toy car, communication device, digital radio.
