NCP5217AGEVB: Synchronous Buck Controller Evaluation Board

NCP5217AGEVB: Synchronous Step-Down Controller Evaluation Board

Overview

The NCP5217A is a synchronous step-down controller for high performance battery-power systems. The NCP5217A includes a high efficiency PWM controller. A pin is provided to enable or disable force PWM mode of operation. An internal power good voltage monitor tracks the SMPS output. NCP5217A also features soft-start sequence, UVLO for VCC and switcher, overvoltage protection, overcurrent protection, undervoltage protection and thermal shutdown. The IC is packaged in QFN-14.
