Bush IC number for LED inverter

[Davy]

Bush CTVL15W15HDVDF 

Been connected incorrectly... too much voltage I'm told. Only apparent damage is smoked LED inverter board with ID markings HQ-LED154-02 Rev1.0.

This is used in a caravan so I *suspect* a reverse polarity connection

Just a tiny board with a handful of parts.... I can see one cap has 'popped it's clogs' and the IC's been puffing away at an Havana cigar and left a trail.

Looking for a source for this board or U1 the IC number which  is unreadable..... gotta start somewhere, the rest looks and checks intact, looks like the micro is calling the shots here!
