Introduction
The LTC3255 is a switched-capacitor step-down DC/DC converter that produces a regulated output (2.4V to 12.5V adjustable) from a 4V to 48V input. In applications where the input voltage exceeds twice the output voltage, 2:1 capacitive charge pumping extends output current capability beyond input supply current limits. At no load, Burst Mode operation cuts VIN quiescent current to 16μA. With its integrated VIN shunt regulator, the LTC3255 excels in 4mA to 20mA current loop applications. The device enables current multiplication; a 4mA input current can power a 7.4mA load continuously. Alternatively, the LTC3255 serves as a higher efficiency replacement for linear regulators and provides a space-saving inductorfree alternative to buck DC/DC converters. The LTC3255 withstands reverse-polarity input supplies and output short-circuits without damage. Safety features including current limit and overtemperature protection further enhance robustness. The LTC3255 is available in thermally enhanced 10-lead MSOP and low profile 3mm × 3mm 10-lead DFN packages.
