IS-1825ASRH, ISL71823ASRH

Data Sheet

September 25, 2008

FN9065.3

Single Event and Total Dose Hardened,

High-Speed, Dual Output PWMs

The single event and total dose hardened IS-1825ASRH and

ISL71823ASRH pulse width modulators are designed to be

used in high frequency, switching power supplies in either

voltage or current-mode configurations. Both designs

include a precision voltage reference, a low power start-up

circuit, a high frequency oscillator, a wide-band error

amplifier and a fast current-limit comparator.

The IS-1825ASRH features dual, alternating outputs

operating from zero to less than 50% duty-cycle, while the

ISL71823ASRH features dual, in-phase outputs operating

from zero to less than 100% duty cycle.

Constructed with the Intersil 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 5962-02511. A “hot-link” is provided

on our website for downloading the SMD.
