ISL6753
ZVS Full-Bridge PWM Controller
The ISL6753 is a high-performance, low-pin-count
alternative zero-voltage switching (ZVS) full-bridge PWM
controller. Like the ISL6551, 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. Compared to the more
familiar phase-shifted control method, this algorithm offers
equivalent efficiency and improved overcurrent and light-
load performance with less complexity in a lower pin count
package.
This advanced BiCMOS design features low operating
current, adjustable oscillator frequency up to 2MHz,
adjustable soft-start, internal over temperature protection,
precision deadtime and resonant delay control, and short
propagation delays. Additionally, Multi-Pulse Suppression
ensures alternating output pulses at low duty cycles where
pulse skipping may occur.

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.
