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 R DS(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 kHz to 750 kHz.
This gives the designer more flexibility to make efficiency and
component size compromises. The NCP5211 will operate over a 4.5 V
to 14 V range using either single or dual input voltage.
