IS-1845ASRH

Single Event Radiation Hardened

High Speed, Current Mode PWM

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.

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.
