LTC3313 Datasheet 15a Synchronous Step-down Silent Switcher

Manufacturer: Analog Devices

Overview: LTC3313 5V, 15A Synchronous Step-Down Silent Switcher in 3mm × 3mm.

General 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.

For systems with higher power requirements, multiphasing parallel converters is readily implemented.
