This device is housed in a SOIC-8 package and operates across a -40\u00b0C ~ +125\u00b0C. It supports a supply voltage range of 7.8V ~ 16V. The component meets industry standards for reliability and is suitable for demanding applications.","working_principle":"The PWM controller uses current-mode control for off-line flyback converters. An internal high-voltage startup current source charges the VCC capacitor, eliminating external startup resistors. Current-mode operation provides inherent pulse-by-pulse current limiting and good audio susceptibility. When output power drops below the skip-cycle threshold, the controller enters burst mode to minimize standby power consumption.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Adj<\/td><td>Skip Cycle Adjust<\/td><\/tr><tr><td>2<\/td><td>FB<\/td><td>Feedback Input<\/td><\/tr><tr><td>3<\/td><td>CS<\/td><td>Current Sense Input<\/td><\/tr><tr><td>4<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>5<\/td><td>DRV<\/td><td>Gate Drive Output<\/td><\/tr><tr><td>6<\/td><td>VCC<\/td><td>Supply Voltage<\/td><\/tr><tr><td>7<\/td><td>NC<\/td><td>No Connect<\/td><\/tr><tr><td>8<\/td><td>HV<\/td><td>High Voltage Startup<\/td><\/tr><\/table>","application_scenarios":"<ul>\n<li>AC-DC\u9002\u914d\u5668<\/li>\n<li>\u79bb\u7ebf\u7535\u6c60\u5145\u7535\u5668<\/li>\n<li>\u8f85\u52a9\u7535\u6e90(USB\/\u5bb6\u7535\/TV)<\/li>\n<li>SMPS\u53cd\u6fc0\u7535\u6e90<\/li>\n<\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Notes<\/th><\/tr><tr><td>NCP1203D40R2G<\/td><td>40kHz\u7248<\/td><\/tr>\n<tr><td>NCP1203D100R2G<\/td><td>100kHz\u7248<\/td><\/tr>\n<tr><td>UC3842<\/td><td>\u517c\u5bb9\u5347\u7ea7<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/3626","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=3626"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/3626\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=3626"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=3626"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=3626"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=3626"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
