IS-1845ASRH Description

The IS-1845ASRH is 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.

Constructed with Intersil's Rad Hard Silicon Gate (RSG) dielectrically isolated BiCMOS process, these devices are immune to single event latch-up and have been specifically designed to provide a high level of immunity to single event transients. All specified parameters are guaranteed and tested for 300krad(Si) total dose performance.

Detailed Electrical Specifications for these devices are contained in SMD 5962-01509. A "hot-link" is provided on our website for downloading the SMD.
