ISL6740A
ISL6740A is Flexible Double-Ended Voltage-Mode PWM Controller manufactured by Renesas.
feature patible with the ISL6740 double-ended pulse width modulating (PWM) voltage-mode controller, allowing easy drop-in replacement on existing designs.
Voltage feed forward pensates 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.
In addition to voltage feed forward pensation, the ISL6740A features an extremely flexible oscillator that allows precise control of frequency, duty cycle, and deadtime. Deadtimes of under 40ns are easily achievable.
This advanced Bi CMOS design features low operating current, adjustable switching frequency...
