Product Overview

The LTC3411EDD#PBF is a constant frequency synchronous step-down DC-to-DC Converter intended for medium power applications. It operates from a 2.63 to 5.5V input voltage range and has a user configurable operating frequency up to 4MHz, allowing the use of tiny, capacitors and inductors 2mm or less in height. The output voltage is adjustable from 0.8 to 5V. Internal synchronous 0.11R power switches with 1.6A peak current ratings provide high efficiency. The LTC3411's current-mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. The LTC3411 can be configured for automatic power saving Burst Mode® operation to reduce gate charge losses when the load current drops below the level required for continuous operation. For reduced noise and RF interference, the SYNC/MODE pin can be configured to skip pulses or provide forced continuous operation.
  • Stable with ceramic capacitors
  • Current-mode operation for excellent line and load transient response
  • Short-circuit protection
  • Synchronizable to external clock
  • 100% Duty cycle of low dropout operation
  • Low shutdown current of IQ <=1µA
  • Up to 95% high efficiency
  • 60µA Low quiescent current
