Product Summary

The LTC3411EMS#TRPBF is a constant frequency, synchronous, step- down DC/DC converter. Intended for medium power applications, the LTC3411EMS#TRPBF operates from a 2.63V to 5.5V input voltage range and has a user configurable operating frequency up to 4MHz, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height. The output voltage is adjustable from 0.8V to 5V. Internal sychronous 0.11Ω power switches with 1.6A peak current ratings provide high efficiency. The LTC3411EMS#TRPBF’s current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. The applications of the LTC3411EMS#TRPBF include Notebook Computers, Digital Cameras, Cellular Phones, Handheld Instruments and Board Mounted Power Supplies.
