Application Notes
- U-135 The UC3848 Average Current Mode Controller Squeezes Maximum PerformancePDF, 267 Kb, File published: Sep 5, 1999
This application note describes the UC3848 average current mode PWM controller. The unique features of this controller are discussed, which make primary side average current-mode control practical for isolated converters. The UC3848 employs a current waveform synthesizer that monitors switch current and simulates the inductor-current down-slope, generating a complete current waveform without actua - U-140 Average Current Mode Control of Switching Power SuppliesPDF, 325 Kb, File published: Sep 5, 1999
Current-mode control, as usually implemented in switching power supplies, actually senses and controls peak inductor current. This process causes many serious problems, including poor noise immunity, a need for slope compensation, and peak-to-average current errors that the inherently low current-loop gain cannot correct. Average current-mode control eliminates these problems and may be used effec
