IR1110 Description

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. prehensive line status fault output including 1/3 phase loss and high or low line fault provides...
