Product Details

The MAX8569 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board demonstrating the MAX8569A or MAX8569B 200mA step-up boost converter. The EV kit comes with the MAX8569B installed. The application circuits provide a 3.3V output voltage capable of sourcing a maximum of 200mA load current from a 1.5V to 5.5V input source. The MAX8569 features internal MOSFETs to reduce cost and size. It also includes skip mode, which optimizes efficiency at light loads to improve battery life. The MAX8569 EV kit can also be used to evaluate the MAX8569A and MAX8569B30 with minor PCB modification.

Applications

Battery Backup
Cordless Phones
Digital Cameras
Local 3.3V to 5V Supplies
Medical Diagnostic Equipment
PC Cards
PDAs and Smartphones
