Single Event Radiation Hardened
High Speed, Current Mode PWM
Features
• Electrically Screened to DSCC SMD # 5962-01509
• QML Qualified per MIL-PRF-38535 Requirements
The IS-1845ASRH is designed to be
used in switching power supplies
operating in current-mode. The

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.

NOTES:
1. Grounding the Comp pin does not inhibit the output. The output
may be inhibited by applying >1.2V to the ISENSE pin.
2. This part should be operated with CT=3.3nF and RT=10k timing
components only.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
