Details & notes

This power module contains the function of automatic buck-boost and integrates with the related circuit of
buck-boost converter. Its mini body is very easy for embedding. Input voltage range 2.5-15V, fixed output
voltage 3.3V, 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 and is suitable for the occasions with high requirements. You can use this power
module to DIY mobile power bank and provide constant power for your project. FEATURES Small size, stable
performance, wide voltage range for a variety of DIY applications APPLICATIONS Power supply for controller
main-board, DIY current source, floodlight, DIY toy car, communication device, digital radio. Serial number

With or Without Isolation: Without Isolation Service Life: 30000h Dimension : 17×13mm/0.67×0.51inch NOTE The
input voltage must within 15V. Load current should not be in 600mA or above for a long time, otherwise it will
affect the service life of the module and even burn out. If the load current is relatively high, you should
increase the minimum input voltage to ensure normal operation. SHIPPING LIST DC-DC Automatic Step Up-down
