This designed as a high-performance module that provides superior function compared to common modules. These are controller chips with onboard ultra-compact PFM control. Any dc voltage of 0.9V to 5V will generate a stable output 5V DC voltage for an output current of 600mA. It uses two AA batteries as input to a single AA battery-powered output with a current 200 mA. As a result, used in mobile phones, cameras, single-chip, digital products only. Here the USB interface can be directly powered with USB female versatile. This module provides overload and over-voltage protection and also short circuit protection into a state below 2.5V. Thereby offers better protection for the module and thus avoids excessive discharge. This module offers a conversion efficiency of 96% providing low ripple factor.
This module widely used In order to power your electronic devices when your device needs 5V power supply. Or when we are using a lithium battery, this module can be directly step-up to 5V. Also used in DIY a mobile power supply, which needs one battery with 5v output such as for your phone, MP3, MP4, PSP charger, very easy. This USB mobile DC step-up module uses a standard USB interface, which supports all universal USB charging mobile phones, MP3, MP4, and other equipment. The module consists of an on-board LED which indicates the charging status when USB is charging.
