problems with SG2525 - diyAudio
May 18, 2008 · That is, the outputs should be on for 50% of what is maximally possible with a half-bridge. The reason for letting the transformer relax for 50% of the time, is that both phases drive the Xfmr in the same direction of flux.

SG2525 - Voltage Mode PWM - STMicroelectronics
The on-chip + 5.1 V reference is trimmed to ±1 % and the input common-mode range of the error amplifier includes the reference voltage eliminating external resistors. A sync input to the oscillator allows multiple units to be slaved or a single unit to be synchronized to an external system clock.
