NE1118
NE1118 is PWM controller manufactured by NEM.
NE1118 12V/3A COC V5.0 Tier2 &DOE V6.0 Design NEM Confidential The NE1118 is a highly integrated PWM controller. It is built-in with several Features to enhance the performance of off-line power supply in SOP-8 package. With the adjustable OPP function integrated in HV pin, it is easy to design the over power protection well under high/low line condition - Turbo boost technology during over load or peak load condition Power boost in a specific period - HV startup with low leakage current, Brown out function. Increased frequency during peak load operation to avoid - Safety Protection: Vcc-GND short test, LPS limitation. transformer saturation. - Supplementary bias charging during load transient - Low power consumption through x-cap discharge switch - System Open Loop Protection - Output Short Circuit Protection - Internal 8m S Soft Start Time Period - Internal 240n S Leading Edge Blanking+500m A/-800m A Gate Drive Capability Various functions on HV pin - Supplemental bias charging from HV pin - HV start-up circuit for lower power consumption. - Internal Brown-in/ out. - X-cap discharge. Protection for LPS. - Frequency Jittering for EMI Reduction - Internal Slope pensation with Self Detection - Peak power with Frequency Double to prevent from Tr. Saturation - Meet Pb-Free, Halogen Free and Ro HS pliant NEM Confidential Typical Application NEM Confidential 引腳分配及封裝...
