IS-1825ASRH, ISL71823ASRH
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.
