Overview
[AP4460A] AP4460A Step-up DC-DC Converter with Power Path for Single Solar Cell 1.
General Description The AP4460A is a synchronous step-up DC-DC converter that can be operated by a single solar cell.
It has a power management function which supplies power to an external system, charges super capacitors, or supplies power from the super capacitor to the system.
The DC-DC converter is a hysteric comparator type and composed of an ultra-low power start-up circuit which starts from only 0.
35 V.
Because the power consumption is extremely low, the AP4460A can operate from the input power of around 50μW generated by a solar panel under indoor lighting.
The input voltage of the DC-DC converter, i.
e.
output voltage of the solar cell is controlled by external resistors for the reference voltage of the IC.
The best power efficiency can be obtained by adjusting this input level setting according to the characteristics of a connected solar cell.
The AP4460A has a Power-Path Control switches for...
