♦LED lamp power supply using frequency, pulse modulation, system feedback constant current mode.
♦LED lamp control design into dormancy and wake up automatic control (Standby loss less than 50 uA).
♦This design input power supply for adaptive structure, automatically adapt to any power supply voltage higher than battery limit or charging. (Such as adapter, solar panel, car cigar plug etc.)
Features:
>Charging & USB indicator
>Low battery warning indicator-flash LED
>USB DC5V 500mA output socket (1000mA max)
>Avoid battery drain during storage
>Protection: Intelligent CPU power management & control system for Dual Protection (Over-charge & Over-discharge) & Balance
