Also, national.com are on record as saying they "dont do offline controllers"........but if LM5039 does what it purports to do, it would literally be the best offline halfbridge controller on the planet.......since FvM also tells that it can be used for offline by using external gate driver.
It is puzzling me why they are not mentioning the offline capability of LM5039 and other PWM ic's of their stock of controllers........do they just not want to sell their stock in larger numbers?
