Product Overview

The LTC3255HDD#PBF is a switched-capacitor step-down DC/DC charge-pump Converter that produces a regulated output from a 4 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 4 to 20mA current loop applications. The device enables current multiplication of 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 inductor-free alternative to buck DC/DC converter. The LTC3255 withstands reverse-polarity input supplies and output short-circuits without damage. Safety features including current limit and over temperature protection further enhance robustness.
  • Multimode charge pump with automatic mode switching maintains regulation over wide VIN range
  • Input voltage shunt mode for current-fed
  • Power good output
  • Over temperature and short-circuit protection
  • -52 to 60V Input fault protection
  • 16µA Quiescent current in regulation at no load
