LTC3313 - 15A Synchronous Step-Down Silent Switcher

Datasheet Summary

Description

The LTC®3313 is a very small, low noise, monolithic step-down DC/DC converter capable of providing up to 15A of output current from a 2.25V to 5.5V input supply.

The device employs the Silent Switcher architecture to achieve both low EMI and high efficiency at switching frequencies as high as 5MHz.
