The NXP® MC34717 is a highly integrated, space-efficient, low cost, dual synchronous buck switching regulator with integrated N-channel power MOSFETs. It is a high performance dual point-of-load power supply with enhanced features for 3.3 V and 5 V environments.
Both channels can provide up to 5 A of continuous output current capability with high efficiency and tight output regulation
The second channel has the ability to track an external reference voltage in different configurations
The MC34717 offers you the flexibility of control, supervisory, and protection functions to allow easy implementation of complex designs
