LTC3407-2 Datasheet (Linear Technology) - 2.25MHz Step-Down DC/DC Regulator

LTC3407-2, 2.25MHz Step-Down DC/DC Regulator

The LTC®3407-2 is a dual, constant-frequency, synchronous step down DC/DC converter.

Intended for low power applications, it operates from 2.5V to 5.5V input voltage range and has a constant 2.25MHz switching frequency, allowing the use of tiny, low cost capacitors and inductors with a proﬁle ≤1.2mm
