NCP1377DR2

The NCP1377DR2 combines a true current mode modulator and a demagnetization  detector which ensures full borderline/critical Conduction Mode in any load/line conditions together with minimum drain voltage switching (Quasi-Resonant operation).

The features of NCP1377DR2 can be summarized as:(1)Pb-Free Package is Available; (2)Free-Running Borderline/Critical Mode Quasi-Resonant Operation; (3)Latched Overvoltage Protection; (4)Auto-Recovery Short-Circuit Protection Via UVLO Crossover; (5)External Latch Triggering, e.g. Via Overtemperature Signal; (6)Current-Mode with Adjustable Skip Cycle Capability; (7)Internal 1.0 ms Soft-Start; (8)Internal Temperature Shutdown; (9)Internal Leading Edge Blanking; (10)500 mA Peak Current Source/Sink Capability; (11)Under Voltage Lockout Level of 12.5 V (On) and 7.5 V (Min); (12)Direct Optocoupler Connection; (13)SPICE Models Available for TRANsient Analysis; (14)Internal Minimum TOFF.
