Overview

High Efficiency, Synchronous Step-Down Controller DESCRIPTION The EUP7117 is a high-efficiency, low power synchronous buck controller for a core logic power supply in notebook applications.
Two external N-channel MOSFETs are needed by the controller to generate an output voltage as low as 0.
75V and output current up to 15A from an input supply (1.
8V to 28V).
EUP7117 features two operation modes: the pulse-skipping mode for high efficiency at light load and the forced PWM mode for low noise applications.
The EUP7117 automatically adjusts operating frequency to achieve fast transient response during load transient.
EUP7117 has built in output monitoring, positive and negative current limit, ov...
