The 48% maximum duty cycle limits the on-time per cycle, which matters for flyback designs where the transformer reset voltage sets the maximum duty before core saturation. ## Supply rail and temperature envelope Operating from 7.6 V to 30 V on Vcc, the TL2845D-8 starts cleanly from a 12 V bias rail and tolerates the ripple of a bootstrap winding in a flyback without an external LDO.","metaTitle":"TL2845D-8 PWM Controller, Boost/Flyback/Forward, 500kHz","metaDescription":"Texas Instruments TL2845D-8 current-mode PWM controller, active production, 7.6-30V supply, up to 500kHz, 8-SOIC.
