[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.
