Following the starting edge of a PWM on time, under normal conditions, the next on time is initiated following the first zero crossing at ZCD after tS. The value of tS is modulated by IFB between a minimum of tS(HF) and a maximum of tS(LF) In normal operation, tS(HF) sets the maximum operating frequency of the power supply and tS(LF) sets the minimum operating frequency of the power supply. 6 Submit Documentation Feedback Copyright © 2009–2015, Texas Instruments Incorporated Product Folder Links: UCC28610 |
