NCP5217A

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.
