NCP1377B
features a sampling time of 4.5 ms whereas it is 1.5 ms for the B version.
The NCP1377 also features an efficient protective circuitries which, in presence of an overcurrent condition, disables the output pulses and enters a safe burst mode, trying to restart. Once the default has gone, the device auto- recovers. Finally an internal 1.0 ms Soft- Start eliminates the traditional startup stress.
