Data Sheet

FN9065.1  
Single Event and Total Dose Hardened,  
High-Speed, Dual Output PWM  
Features  
• Electrically Screened to DSCC SMD # 5962-02511  
The single event and total dose hardened IS-1825ASRH  
pulse width modulator is designed to be used in high  
frequency, switching power supplies in either voltage or  
current-mode configurations. The design includes 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 use of proprietary process  
capabilities and unique design techniques results in fast  
propagation delay times and high output current over a wide  
range of output voltages.  
• QML Qualified per MIL-PRF-38535 Requirements  
• Radiation Environment  
- Total Dose. . . . . . . . . . . . . . . . . . . . . 300krad(SI) (max)  
- Latch-up Immune . . . . . . . . . . . . . Dielectrically Isolated

- SEU immune . . . . . . . . . . . LET=35MeV/mg/cm (max)  
• Oscillator Frequency . . . . . . . . . . . . . . . . . . . .1MHz(max)  
• High Output Drive Current . . . . . . . . . . . . . . .1A peak(typ)  
• Low Start-up Current . . . . . . . . . . . . . . . . . . . 300µA(max)  
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.  
• Undervoltage Lockout  
- Start Threshold . . . . . . . . . . . . . . . . . . . . . . . .8.8V(max)

- Hysteresis. . . . . . . . . . . . . . . . . . . . . . . . . . 300mV(min)  
• Improved Soft-Start Function Compared with Commercial  
1825A Types  
Detailed Electrical Specifications for these devices are  
contained in SMD 5962-02511. A “hot-link” is provided  
on our website for downloading the SMD.  
• Pulse-by-Pulse Current Limiting  
• Latched Overcurrent Comparator with Full Cycle Restart  
• Programmable Leading Edge Blanking
