DATASHEET ISL6740A Flexible Double-Ended Voltage-Mode PWM Controller with Voltage Feed Forward FN9195 Rev 3.00 February 9, 2012 The ISL6740A is an enhanced ISL6740 PWM controller featuring built-in voltage feed forward functionality. It is pin and feature compatible with the ISL6740 double-ended pulse width modulating (PWM) voltage-mode controller, allowing easy drop-in replacement on existing designs. Voltage feed forward compensates for input voltage variation without intervention of the feedback control loop. It is particularly useful in unregulated bus converters and DC transformers where wide input voltage variation would otherwise result in large output voltage swings.
