The CXSD62397 provides complete control and protection for a DC-DC converter for high power applications. It is designed to drive two N-channel MOSFETs in a synchronous-rectified buck topology. The CXSD62397 integrates all of the control, bootstrap diode and protection functions into a single package. The CXSD62397 provides simple, single feedback loop, voltage-mode control with fast transient response. It includes a 300kHz free-running triangle-wave oscillator. The error amplifier features a 15MHz gain-bandwidth product which provides high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0% to 80%. The reference voltage is 0.8V, 2% accuracy. The CXSD62397 has internal soft start and executes cycle-by-cycle current limit during soft start interval. The CXSD62397 monitors the current by using the RDS(ON) of the low-side MOSFET which eliminates the need for a current sensing resistor. The under-voltage protection function monitors voltage at FB pin. The over-current and under-voltage events after soft-start interval trigger hiccup mode protection.
