The SQ33065 is 75V synchronous buck controller with type Ⅲ voltage mode control and feedforward.
Minimum tens of nanosecond on-time facilitates large step-down ratios.
The SQ33065 continues to operate when input voltage decreases to as low as 6V.
VIN over voltage protection is achieved by directly detecting VIN pin voltage to prevent output inverse charging.
Cycle-by-cycle over current protection is accomplished by measuring the voltage across the lowside MOSFET or current sense resistor.
Forced-PWM (FPWM) eliminates frequency variation and a selectable diode emulation lowers power consumption at light-load conditions.
The switching frequency as high as 1 MHz can be set or synchronized to an external clock.
