Notes:

a. MOC stands for moderate overcurrent voltage at CS pin.

b. SOC stands for severe overcurrent voltage at CS pin.

c. The maximum duty cycle is set by the resistor ratio (RDB1/RDB2) from pin RDB to VREF at minimum VIN = 42 V.

d. Not tested. Guaranteed by driver frequency test. The driver frequency is half of the oscillator frequency.
