FWIW they're rather handy! -- They typically feature a feedback tap such that the power oscillator is implemented via a single BJT sans biasing resistors, etc... --- I have found said devices to be an ultra-compact solution to certain applications 'traditionally' featuring CCFL transformers where only 'flea power' output is required (e.g. PMTs, GM tubes, 'capacitor chargers', neon indicator lamps, etc...) -- Surprisingly, for devices intended for disposable products, they have proven quite reliableThe ones I messed around with had a small PCB size transformer in them, Around a 0.650" cube.
