UC384X, is with 2 diodes voltage offset then feeding into the voltage divider with 1/ 3 ratio, that is, ( V 2 V ) 3 1 V ( PWM COMPARATOR ) u COMP F A pull- high resistor is embedded internally thus can be eliminated on the external circuit. Internal Slope Compensation A fundamental issue of current mode control is the stability. View TI’ s UC3843 datasheet.
