Features and Benefits of LTC3852
Product Detailed Description for LTC3852

The LTC3852 is a constant frequency, current mode step-down DC/DC controller which can be powered by an on-board charge pump. Input supplies as low as 2.7V, when doubled by the charge pump, provide 5V to the LTC3852’s control logic and gate drives, supporting a wide selection of logic-level N-channel power MOSFETs.

The constant-frequency current mode architecture allows for a phase-lockable fixed frequency of up to 750kHz. The RUN pin provides a precision enable threshold while the TRACK/SS pin combines tracking and adjustable soft-start features.

The MODE/PLLIN pin selects among Burst Mode® operation, pulse-skipping mode, and continuous current mode. Current foldback limits MOSFET power dissipation during short-circuit conditions. Reverse current and current foldback functions are disabled during soft-start. A power good output pin indicates when the output is within ±10% of its designed set point.

Applications

  • General Purpose 3.3V Systems
  • Lithium-Ion Powered Devices
  • Distributed DC Power Systems
