Modeling Analysis and Compensation of the Current-Mode Converter
PDF, 189 Kb, Archivo publicado: sept 5, 1999
As current-mode conversion increases in popularity several peculiarities associated with fixed-frequency peak-current detecting schemes have surfaced. These include instability above 50% duty cycle a tendency towards subharmonic oscillation non-ideal loop response and an increased sensitivity to noise. This application note attempts to show that the performance of any current-mode converter c

DN-45 UC3846 UC3856 and UCC3806 Push Pull PWM Current Mode Control ICs
PDF, 27 Kb, Archivo publicado: sept 5, 1999
The UC3856 is a pin-for-pin-compatible high-performance bipolar version of the industry standard UC3846. It can replace the UC3846 with few circuit modifications and it features increased speed higher gate-drive current and reduced propagation delays. The UCC3806 is a BiCMOS pin-for-pin compatible ultra-low-power version ideal for battery low-power and high-speed applications. The UCC3806
