EVIX-USB

The EVIX-USB is a solarbit evaluation board. The evaluation board uses IXOLAR bits, rechargeable AA alkaline cells, and a DC/DC converter to generate a regulated 5V output that can operate or charge USB appliances. The XOB17-12x1 Solarbits are monocrystalline, high efficiency solar cells in a surface mount package that can be reflow soldered. They are extremely robust and can be used in harsh environments. Solarbits have a very high (17%) power conversion efficiency, which means that 17% of the light energy is converted into electrical energy. They are extremely useful in applications requiring solar power generation in a limited space. IXYS cells can be used in indoor and outdoor applications because they have a wide spectral sensitivity, 300nm to 1100nm. However, the output power of a solar cell is proportional to the incoming light energy, and irradiance is generally much higher outdoors.

• Eight series connected Solarbits
• Converter IC boosts the battery voltage to 5V
• The AA cells will charge any time the solar bits are exposed to daylight
• Push on jumper from OFF to ON to operate the converter and generate 5V
