NCP5212A, NCP5212T

Single Synchronous

Step-Down Controller

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

and switcher, overvoltage protection, overcurrent protection,

undervoltage protection and thermal shutdown. The IC is packaged in

QFN16
