General Description
The MAX5066 is a two-phase, configurable single- or dual-output buck controller with an input voltage range of 4.75V to 5.5V or from 5V to 28V. Each phase of the MAX5066 is designed for 180° operation. A mode pin allows for a dual-output supply or connecting two phases together for a single-output, high-current supply. Each output channel of the MAX5066 drives n-channel MOSFETs and is capable of providing more than 25A of load current.
