[AP2200B] MS1613-E-01 2014/04 - 1 - 1. General Description The AP2200B is a voltage step-up DC-DC converter that uses a synchronous rectification method to be activated with a dye-sensitized solar cell. It is ideal for charging lithium-ion capacitors and outputting 3V. 2. Features Input voltage range 0.3V to 1.6V MPP input setting voltage 0.4V Operating temperature range -30 to 85 ºC Input power Up to 400mW Output voltage 3.0V(±2.0%) (SEL pin = “L”) 3.8V(±5.0%) (SEL pin = “H”) Control method Comparator control method Rectification method Synchronous rectification method Standby function When the STBY pin is “H”, the LC pin is fixed to “H” No battery detect function When the VB pin voltage decreases, the LC pin is fixed to “H”. Efficiency 70% (3.8V, 50mA output) Package 16-pin QFN Application For outputting and charging 3V with a dye-sensitized solar cell, charging a lithium-ion capacitor Step-Up DC -DC Converter IC Supporting Dye -sensitized Solar Cell AP2200B
