Overview

The NCP5424 is a flexible dual N-channel synchronous buck controller utilizing V2 control for fast transient response and excellent line and load regulation. This highly versatile controller can be configured as a single two phase output converter that draws programmable amounts of current from two different input voltages or all current from one supply. The NCP5424 can also be configured as two independent out-of-phase controllers.
