Product Summary

The IR115IS is a power factor correction (PFC) control IC designed to operate in continuous conduction mode (CCM) over a wide range input line voltages. The IR115IS is based on proprietary "One Cycle Control" (OCC) technique providing a cost effective solution for PFC. The proprietary control method allows major reductions in component count, PCB area and design time while delivering the same high system performance as traditional solutions. The IR115IS is fully protected and eliminates the often noise sensitive line voltage sensing requirements of existing solutions.

Parametrics

IR115IS absolute maximum ratings: (1)VCC voltage VCC: -0.3 to 22V; (2)Freq. voltage VFREQ: -0.3 to 10.5V; (3)ISNS voltage VISNS: -10 to 3V; (4)VFB voltage VFB: -0.3 to 10.5 V; (5)COMP voltage VCOMP: -0.3 to 10 V; (6)Gate voltage VGATE: -0.3 to 18 V; (7)Continuous gate current IGATE: -5 to 5mA; (8)Max peak gate current IGATEPK: -1.5 to 1.5A; (9)Junction temperature TJ: -40 to 150℃; (10)Storage temperature TS: -55 to 150℃; (11)Thermal resistance RθJA: 128℃/W; (12)Package power dissipation PD: 675mW; (13)ESD protection VESD: 2kV.
