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 is used to achieve unmatched transient response, the best overall regulation and the simplest loop compensation. Additionally, the CS5212 provides overcurrent protection, undervoltage lockout, soft−start, built−in adaptive non−overlap, and an adjustable fixed frequency range of 150 kHz to 750 kHz, which gives the designer more flexibility to make efficiency and component size trade offs. The CS5212 will also operate over a 3.1 V to 7.
