Product Summary
The LTC3204EDC-5 is the low noise, constant frequency (1.2MHz) switched capacitor voltage doubler. The LTC3204EDC-5 can produce a regulated output voltage of 3.3V from a minimum input voltage of 1.8V (2 alkaline cells) whereas the LTC3204EDC-5 can produce 5V from a minimum of 2.7V (Li-Ion battery) input. The LTC3204EDC-5 features automatic Burst Mode operation at light loads to maintain low supply current whereas it features constant frequency operation at any load. Built-in soft-start circuitry prevents excessive inrush current during start-up. Thermal shutdown and current-limit circuitry allow the parts to survive a continuous short-circuit from VOUT to GND.
