ISL6740A
Flexible Double-Ended Voltage-Mode
PWM Controller with Voltage Feed
Forward
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.
In addition to voltage feed forward compensation, 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 BiCMOS design features low operating
current, adjustable switching frequency up to 1MHz,
adjustable soft-start, internal and external over temperature
protection, fault annunciation, and a bidirectional SYNC
signal that allows the oscillator to be locked to paralleled
units or to an external clock for noise sensitive applications.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
