NCP5212A
NCP5212A is Single Synchronous Step-Down Controller manufactured by onsemi.
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 VCC and switcher, overvoltage protection, overcurrent protection, undervoltage protection and thermal shutdown. The IC is packaged in QFN16
