Dual Step-Down Regulator

Description

The LTC3774 is a dual output buck converter that enhances the signal-to-noise ratio and can operate with a small sense signal of a very low value inductor DCR to improve power efficiency, and reduce jitter due to the switching noise. The circuit uses two high frequency gate driver LTC4449, designed to drive two N-Channel MOSFETs in a synchronous DC/DC converter. In this SPICE simulation the input voltage is 12V and the two supplies are 1.5V 30 ampere and 1.2V 30 ampere.
