MAX8973A Description
The MAX8973A high-efficiency, three-phase, DC-DC step-down switching regulator delivers up to 9A of output current in a pact footprint with excellent transient response. Each phase operates at a 2MHz fixed frequency, allowing the use of small magnetic ponents. Maxim Integrated’s proprietary Rotational Phase Spreading algorithm optimizes efficiency at low output currents.
