NCP5211
NCP5211 is Low Voltage Synchronous Buck Controller manufactured by onsemi.
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- Start and built in adaptive nonoverlap. The NCP5211 also provides adjustable fixed frequency range of 150 k Hz to 750 k Hz. This gives the designer more flexibility to make efficiency and ponent size promises. The NCP5211 will operate over a 4.5 V to 14 V range using either single or dual input voltage.
