DATASHEET  
Single Event and Total Dose Hardened, High-Speed,  
Dual Output PWMs  
IS-1825ASRH, IS-1825BSRH, IS-1825BSEH, ISL71823ASRH,  
ISL71823BSRH  
The single event and total dose hardened pulse width  
modulators are designed to be used in high frequency,  
Features  
• Electrically screened to DLA SMD# 5962-02511  
• QML qualified per MIL-PRF-38535 requirements  
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.  
• EH version is wafer-by-wafer acceptance tested to  
50krad(Si) (LDR)  
• Radiation environment  
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

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.
