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.
Features
• Free−Running Borderline/Critical Mode Quasi−Resonant Operation
• Latched Overvoltage Protection
• Auto−Recovery Short−Circuit Protection Via UVLO Crossover
• External Latch Triggering, e.g. Via Overtempe.
