ISL6551 is a PWM controller designed for the zero -voltage switch (ZVS) full bridge. This part implements a unique fixed -frequency ZVS current mode control algorithm, which has high control efficiency and low electromagnetic interference. Two lower drivers are delayed by the vein width modulation control from the vein width modulation control. The integrated circuit integrates the 6X6 square millimeter QFN and 28 lead SOIC packaging to generate a complete and complex power solution. The control function includes the programmable soft start of the control start, the programmable resonance delay of the zero -voltage switch, the peak of the current slope of the PWM comparator triggered by the front edge of the front edge of the front edge, and the adjustable slope compensation of the slope to achieve synchronization synchronization The high output current, the ultra -high -efficiency rectifier application and the current sharing support 10 units, which helps to achieve higher reliability and availability and better thermal management. Protective functions include adjustable peak -time peak current current limit protection, fast short circuit protection (in snoring mode), a lock -up and input of a shutdown circuit completely turn on the output over -voltage conditions or other extremes and unwilling faults, non -expected, non -expected failure, non -expected, non -expected failure, non -expected, non -expected failure, non -expected, non -expected failure, non The atresia enable input receives the voltage and thermal state of the Enable command converter when monitoring input, and the voltage lag locking. In addition, the ISL6551 includes a large -current high -side and low -side totem column to avoid the driver capacitance of the middle door additional external driver (up to 1.6NF at 1MHz). The operating conditions of the band benchmarking tolerance exceeded ± 1.5%(ISL6551AB) or ± 1%(ISL6551ib), and the supervision monitoring.
