The LTC3856 is a versatile and feature-rich single-output 2-phase synchronous buck controller with on-chip drivers, remote output voltage sensing, inductor DCR temperature compensation, Stage Shedding™ mode and active voltage positioning (AVP).
The document describes the design features of the LTC3856, a versatile single-output 2-phase synchronous buck controller. It includes on-chip drivers, remote output voltage sensing, inductor DCR temperature compensation, and Stage Shedding mode for high efficiency.
Key features include active voltage positioning (AVP) to improve transient response, programmable stage shedding to reduce switching losses at light loads, and the ability to operate up to 12-phase by combining multiple units. The controller supports input voltages from 4.5V to 38V.
The controller can convert inputs ranging from 4.5V to 38V.
The device can produce outputs up to 5V.
Up to six LTC3856s can be combined for this purpose.
