Solar Lamp Controller

0116 Solar LED Lamp Controller

0116 is a solar LED lamp controller with one battery, in which solar-charging and LED-driving sections are included: the former can help to detect voltage on the solar cell, control the charging process and prevent the reversely charging from battery to solar cell etc; the later has the functions of detecting status of battery, producing 100KHz pulse-train, being in standby mode manually and limiting the peak driving current etc. Only an external inductor is needed to construct a booster-type switching power supply with over 90% of charging efficiency and driving efficiency. 0116 has the advantages of high efficiency, low power dissipation, low minimum operating voltage 0.8V and realizing the charging and LED-driving functions automatically etc. Hence, it is especially suitable for the lighting applications with one battery, like outdoor solar lawn-lamp and street-light etc
