Description

The NCP5212A/NCP5212T is a synchronous stepdown 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, overvoltage protection, overcurrent protection,undervoltage protection and thermal shutdown. The IC is packaged in QFN16
