Description

  • Typical Application for LTC3411A - 1.25A, 4MHz, Synchronous Step-Down DC/DC Converter. The LTC3411A is a constant frequency, synchronous step-down DC/DC converter. Intended for medium power applications, it operates from a 2.5V 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 1mm or less in height. The output voltage is adjustable from 0.8V to 5.5V. Internal synchronous power switches provide high efficiency. The LTC3411A's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors

Key Features

  • Conversion Type
    DC to DC
  • Output Current
