October 16, 2015 Features The IS-1845ASRH, IS-1845ASEH are designed to be used in
switching power supplies operating in current-mode. The rising
edge of the on-chip oscillator turns on the output. Turn-off is
controlled by the current sense comparator and occurs when
the sensed current reaches a peak controlled by the error
amplifier. Electrically Screened to DSCC SMD # 5962-01509 QML Qualified per MIL-PRF-38535 Requirements Radiation Environment
