功能描述

The LTC3204-3.3/LTC3204-5/LTC3204B-3.3/LTC3204B-5 are low noise, constant frequency (1.2MHz) switched ca-pacitor voltage doublers. The LTC3204-3.3/LTC3204B-3.3 can produce a regulated output voltage of 3.3V from a minimum input voltage of 1.8V (2 alkaline cells) whereas the LTC3204-5/LTC3204B-5 can produce 5V from a minimum of 2.7V (Li-Ion battery) input.

LTC3204-3.3/LTC3204-5 feature automatic Burst Mode operation at light loads to maintain low supply current whereas LTC3204B-3.3/LTC3204B-5 feature 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.

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

The LTC3204-3.3/LTC3204-5/LTC3204B-3.3/LTC3204B-5 are available in a low pro?le (0.75mm) 6-lead 2mm × 2mm DFN package.
