.. NCP5211A Low Voltage Synchronous Buck Controller The NCP5211A 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 low RDS(on) NFETs for better efficiency. The NCP5211A is in a 14 pin package to minimize PCB area. The NCP5211A provides overcurrent protection, undervoltage lockout, soft start and built in adaptive nonoverlap. The NCP5211A is adjustable over a frequency range of 150 k Hz to 750 k Hz. This gives the designer more flexibility to make efficiency and ponent size promises. The NCP5211A will operate on a single supply or a separate boost supply. Features http://onsemi.
