LTC4425-Slide3

The LTC4425 is Linear Technology’s 2nd SuperCapacitor charger (the 1st being the LTC3225/-1), a charge pump doubler with current limiting and automatic cell balancing. The LTC4425 addresses high peak power, data backup and “dying gasp” needs in portable and data storage applications. The device employs a linear constant current, constant voltage charger architecture with onboard ideal diode and thermal limiting to charge two super-capacitors in series to a programmable output voltage from a Li-Ion/Polymer battery, a USB port, or other 2.7V to 5.5V current-limited supplies.
