IS-1825ASRH
feature dual, alternating output operating from zero to less than 50% duty cycle, and the ISL71823x SRH 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 Bi CMOS 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.
Applications
- Voltage or current mode switching power supplies
- Control of high current...
