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. 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.
