Overview

NCP5217A Single Synchronous Step-Down Controller The NCP5217A is a synchronous step−down controller for high performance systems battery−power systems.
The NCP5217A includes a high efficiency PWM controller.
A pin is provided to enable or disable forced 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 QFN14.
