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 RDS(on) NFETs for better efficiency.
The V2™ control architecture is used to achieve unmatched transient response, the best overall regulation and the simplest loop compensation.
