ZVS Full-Bridge PWM Controller with
Average Current Limit
The ISL6755 is a high-performance extension of the Intersil
family of full-bridge ZVS controllers. Like the ISL6753, 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 ISL6753’s feature set is average current
monitoring. The signal may be used for average current
limiting, current sharing circuits and average current mode
control.
This advanced BiCMOS design features low operating
current, adjustable oscillator frequency up to 2MHz,
adjustable soft-start, 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.
