Description
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 (tPWM). 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.
