LTC3204-3.3 Description

The LTC3204-3.3 are low noise, constant frequency (1.2MHz) switched capacitor voltage doublers. The LTC3204-3.3 can produce a regulated output voltage of 3.3V from a minimum input voltage of 1.8V (2 alkaline cells).

LTC3204-3.3 feature automatic Burst Mode® operation at light loads to maintain low supply current. 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.

High switching frequency minimizes overall solution footprint by allowing the use of tiny ceramic capacitors. In shutdown, the load is disconnected from the input and the quiescent current is reduced to <1µA.

The LTC3204-3.3 are available in a low profile (0.75mm) 6-lead 2mm × 2mm DFN package.
