Dual Phase Buck Controller Drives High Density 1.2V/60A Supply with Submilliohm DCR Sensing

July 29, 2015 // By Mike Shriver, Linear Technology
Designers of low output voltage rails for communication, networking, server and industrial systems are challenged to achieve greater load currents and higher efficiency in diminishing board space. The LTC®3774 dual output buck controller eases this burden by interfacing easily with DrMOS devices, providing high efficiency and small size by integrating MOSFET and gate driver in the same package. The LTC3774 can sense current across the inductor's DCR, with values as low as 0.2mΩ, improving efficiency by eliminating the need for a discrete sense resistor.
