ISL6755

The ISL6755 is a high-performance extension of the Intersil family of full-bridge ZVS controllers. The features of ISL6755 are as follows: (1)Adjustable Resonant Delay for ZVS Operation; (2)Voltage- or Current-Mode Operation; (3)3% Current Limit Threshold; (4)Adjustable Average Current Limit; (5)175A Startup Current; (6)Supply UVLO.

The following is about the absolute maximum ratings of ISL6755: (1)Supply Voltage, VDD: GND - 0.3V to +22.0V; (2)OUTxxx: GND - 0.3V to VDD; (3)Signal Pins: GND - 0.3V to VREF + 0.3V; (4)VREF: GND - 0.3V to 6.0V; (5)Peak GATE Current: 0.1A; (6)Latchup: Class II, Level B @ +85°C.

The electrical characteristics of the ISL6755 are: (1)Supply Voltage: 20; (2)Start-Up Current, IDD: 175 A typ and 400 A max at VDD = 5.0V; (3)Operating Current, IDD: 11.0mA typ and 15.5mA max at RLOAD, COUT = 0; (4)UVLO START Threshold: 8.00 V min, 8.75 V typ and 9.00 V max; (5)UVLO STOP Threshold: 6.50 V min, 7.00 V typ and 7.50 V max; (6)Hysteresis: 1.75 V; (7)Overall Accuracy: 4.850V min, 5.000V typ and 5.150V max at IVREF = 0mA to -10mA; (8)Long Term Stability: 3mV at TA = +125°C, 1000 hours; (9)Operational Current (source): -10 mA; (10)Operational Current (sink): 5 mA; (11)Current Limit: -15mA min and -100mA max at VREF = 4.85V.
