LTC4425/LTC3533 3.3V at 1.5A from 5V Peak-Power & Back-up Supply using Two Supercapacitors

Mar 15th 2007
The LTC4425 is a constant-current/constant-voltage linear charger designed to charge a 2-cell supercap stack from either a Li-Ion/Polymer battery, a USB port, or a 2.7V to 5.5V current-limited supply. The part operates as an ideal diode with an extremely low 50mΩ on-resistance making it suitable for high peak-power/low ...
