NCP5212AGEVB:  Synchronous Step-Down Controller Evaluation Board

The NCP5212A/NCP5212T is a synchronous step-down controller for high performance systems battery-power systems. The NCP5212A/NCP5212T includes a high efficiency PWM controller. A pin is provided to allow two devices in interleaved operation. An internal power good voltage monitor tracks the SMPS output. NCP5212A/NCP5212T also features soft-start sequence, UVLO for Vcc and switcher, over-voltage protection, over-current protection, under-voltage protection and thermal shutdown. The IC is packaged in QFN16.
