Yeah, use the linkify button in the top right...
Oh, 3525, yeah it's got totem pole outputs (as opposed to the '24 that has "uncommitted BJTs"), oscillator, dead time and an error amp. Handy for building blocks, if not quite ideal for SMPS purposes alone.
There's some older flavors of the same basic function, in part numbers that I forget; the TL494/KA7500 (TI, Fairchild versions, two error amps, BJT output) and TL598 (totem pole), and the upscale UC3525 and such (Unitrode-now-TI made improved versions of a number of parts like this).
As for PP vs H, more power of course. Simpler winding helps. Clamped commutation helps. Eliminates the switching loss due to primary end-to-end leakage inductance.
PP, half and full bridge are the active-switching versions of familiar rectification circuits: FWCT or current doubler, FWB and voltage doubler. Note that the voltage and current doublers are merely the series-parallel, L-C duals of each other, so are actually the same circuit fundamentally.
