NCP5212: Single Synchronous Step Down Controller

Description: NCP5212 is a synchronous step-down controller for ...
  • NCP5212 is a synchronous step-down controller for high performance battery powered systems. It 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. NCP5212 also features soft start sequence, UVLO for Vcc and switcher, overvoltage protection, overcurrent protection, undervoltage protection and thermal shutdown. It is packaged in QFN-16.
