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.


  • Small size, stable performance, wide voltage range for a variety of DIY applications


Power supply for controller main-board, DIY current source, floodlight, DIY toy car, communication device, digital radio.

Note: The input voltage can not exceed 15V

  1. The input voltage must within 15V.
  2. 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.
  3. If the load current is relatively high, you should increase the minimum input voltage to ensure normal operation.
