CS5211
Low Voltage Synchronous
Buck Controller
The CS5211 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 V
2
control architecture is used to achieve
unmatched transient response, the best overall regulation and the
simplest loop compensation. The CS5211 is in a 14–pin package to
allow the designer added flexibility.
The CS5211 provides overcurrent protection, undervoltage lockout,
Soft Start and built in adaptive nonoverlap. The CS5211 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 CS5211 will operate over a 4.5 V to 14 V range
using either single of dual input voltage.
