NCP5212A
Single Synchronous Step-Down Controller
NCP5212A, NCP5212T
Single Synchronous
Step-Down ControllerThe 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
