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.

Features
