The UPS Click Board™ is a supercapacitor charger Click Board™ that provides continuous power for a load connected to the output terminals. It also provides a temporary backup power supply in cases when the main power supply is abruptly disconnected - hence its name - UPS Click Board™.
Besides backup function, it also provides power for the applications with high peak power requirements, such as LED flashes, PCMCIA TX bursts, HDD bursts, GPRS/GSM transmitters and similar. The UPS Click Board™ uses two 3.3F supercapacitors connected in series, which are used as temporary power storage banks.
