Single Event and Total Dose Hardened, High-Speed Dual Output PWMs

The
IS-1825ASRH, IS-1825BSRH, IS-1825BSEH,
ISL71823ASRH,
and
ISL71823BSRH
are single event
and total dose hardened pulse width modulators designed
to be used in high-frequency switching power supplies in
either voltage or current-mode configurations. These
devices 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-1825xSRH and IS-1825xSEH feature dual,
alternating output operating from zero to less than 50%
duty cycle, and the ISL71823xSRH features dual
in-phase output operating from zero to less than 100%
duty cycle. The B versions of the parts test the delay from
clock out to PWM output switching after power has been
applied to the modulator (t
PWM
) (see
Figure 2 on page 9).
The SEH parts are wafer-by-wafer acceptance tested to
50krad(Si) at a low dose rate of <10mrad(Si)/s.
Constructed with the 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
established and tested for 300krad(Si) total dose
performance.
The devices are offered in a 16 Ld CDIP or a 20 Ld
CDFP and fully specified to across the temperature range
of -50°C to +125°C.
