Description

The NCP1337PG 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 transformer core reset detection is done internally, without using any external signal, due to the Soxyless concept. The frequency is internally limited to 130 kHz, preventing the controller to operate above the 150 kHz CISPR−22 EMI starting limit. NCP1337PG Features • Free−Running Borderline/Critical Mode Quasi−Resonant Operation• Current−Mode• Soft Ripple Mode with Minimum Switching Frequency for Standby• Auto−Recovery Short−Circuit Protection Independent of Auxiliary Voltage• Overvoltage Protection• Brown−Out Protection• Two Externally Triggerable Fault Comparators (one for a disable function, and the other for a permanent latch)• Internal 4.0 ms Soft−Start• 500 mA Peak Current Drive Sink Capability• 130 kHz Max Frequency• Internal Leading Edge Blanking• Internal Temperature Shutdown• Direct Optocoupler Connection• Dynamic Self−Supply with Levels of 12 V (On) and 10 V (Off)• SPICE Models Available for TRANsient and AC Analysis• These are Pb−Free Devices* NCP1337PG Applications • AC−DC Adapters for Notebooks, etc.• Offline Battery Chargers• Consumer Electronics (DVD Players, Set−Top Boxes, TVs, etc.)• Auxiliary Power Supplies (USB, Appliances, TVs, etc.)
