LTC3625 Power Backup Using Supercapacitors and Optional Keep-Alive Cell

Apr 1st 2010
The LTC4415 contains two monolithic PowerPath ideal diodes, each capable of supplying up to 4A with typical forward conduction resistance of 50mΩ. The diode voltage drops are regulated to 15mV during forward conduction at low currents, extending the power supply operating range and ensuring no oscillations during supply ...

LTC3625 5V Power Ride Through

Jun 5th 2002
In the event of an interruption to the main power supply, the supercapacitors can power the system for up to several seconds. The diode or controller LTC4412 automatically switches the input of the LTM4616 to the supercapacitors if the 5V power is unavailable. The LTC3625/LTC3625-1 are programmable supercapacitor chargers designed ...

LTC3625/LT1784 Solar Powered Super Capacitor Charger with MPPT

Oct 26th 2000
The input of the LTC3625 can also be driven by many widely available solar cells. In this circuit, MPPT (maximum power point tracking) is implemented by modulating the charge current based on the input voltage of the LTC3625. The LTC3625/LTC3625-1 are programmable supercapacitor chargers designed to charge two supercapacitors ...
