The CS5211 is a low voltage synchronous buck controller. It contains all required circuitry for a synchronous buck converter using external NChannel MOSFETs. High current internal gate drivers are capable of driving high gate capacitance of low RDS(on) NFETs for better efficiency. The V2TM control architecture is used to achieve unmatched transient response, the best overall regulation and the simplest loop compensation. The CS5211 is in a 14pin 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. Features
