NCP5211 Low Voltage Synchronous Buck Controller The NCP5211 is a low voltage synchronous buck controller. It contains all required circuitry for a synchronous buck converter using external N Channel MOSFETs. High current internal gate drivers are capable of driving high gate capacitance of low RDS(on) NFETs for better efficiency. The NCP5211 is in a 14 pin package to allow the designer added flexibility. The NCP5211 provides overcurrent protection, undervoltage lockout, Soft .
