Data Sheet
September 29, 2008
FN6754.1
ZVS Full-Bridge PWM Controller with
Adjustable Synchronous Rectifier Control
The ISL6754 is a high-performance extension of the Intersil
family of zero-voltage switching (ZVS) full-bridge PWM
controllers. Like the ISL6752, it achieves ZVS operation by
driving the upper bridge FETs at a fixed 50% duty cycle while
the lower bridge FETs are trailing-edge modulated with
adjustable resonant switching delays.
Adding to the ISL6752’s feature set are average current
monitoring and soft-start. The average current signal may be
used for average current limiting, current sharing circuits and
average current mode control. Additionally, the ISL6754
supports both voltage- and current-mode control.
The ISL6754 features complemented PWM outputs for
synchronous rectifier (SR) control. The complemented
outputs may be dynamically advanced or delayed relative to
the PWM outputs using an external control voltage.
This advanced BiCMOS design features precision deadtime
and resonant delay control, and an oscillator adjustable to
2MHz operating frequency. Additionally, Multi-Pulse
Suppression ensures alternating output pulses at low duty
cycles where pulse skipping may occur.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is 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.
