The single event and total dose hardened pulse width
Features
modulators are designed to be used in high frequency,
switching power supplies in either voltage or current-mode
configurations. These 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, IS-1825BSRH and IS-1825BSEH feature
dual, alternating output operating from zero to less than 50%
duty-cycle, while the ISL71823ASRH and ISL71823BSRH
features dual, in-phase output operating from zero to less than
100% duty cycle. The “B” versions test the delay from clock out
to PWM output switching after power has been applied to the
modulator (t
PWM
) (see Figure 3). The ISL-825BSEH is
wafer-by-wafer acceptance tested to 50krad(Si) at a low dose
rate of 10mrad(Si)/s.
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.
