SiP11206

Notes:

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

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

c. RDB should be chosen for each application to provide adequate dead time. For production testing RDB is chosen to test at 47 % target duty.

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