INTRODUCTION
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 150uA. 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.
Silkscreen “DM13B” and “DM14” are for Production Base Codes only. Both of them
belong to V2.0, and they have no difference in performance.
