Low Voltage Synchronous Buck Controller

The CS5212 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.
