Product Summary
The IR1110 is a high performance analog IC designed to control ramp rate and voltage of the DC bus from
either single or three phase AC line voltage input. It controls a SCR half bridge and provides robust ride through
capability in event of transient loss of line, and DC bus regulation with eternal reference input. Comprehensive
line status fault output including 1/3 phase loss and highor low line fault provides versatile line diagnostic capability to the system. The IR1110 is based on advanced low power design so it can utilize the SCR snubber derived power supply.
