CS5212 Low Voltage Synchronous Buck Controller

CS5212 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 V2t control architecture i.
