LTC3546 Datasheet (Linear Technology) - 3A/1A or 2A/2A Configurable Step-Down DC/DC Regulator

LTC3546, 3A/1A or 2A/2A Configurable Step-Down DC/DC Regulator

The LTC®3546 is a dual, constant-frequency, synchronous step down DC/DC converter for medium power applications.

The design consists of 2A and 1A primary output switches.

In addition to the 2A/1A capability, a 1A dependant output switch can be externally connected to either of the primary outputs to
