| (R) IS-1845ASRH Data Sheet October 2003 FN9001.3 Single Event Radiation Hardened High Speed, Current Mode PWM The IS-1845ASRH is designed to be used in switching power supplies operating in current-mode. The rising edge of the on-chip oscillator turns on the output. Turn-off is controlled by the current sense comparator and occurs when the sensed current reaches a peak controlled by the error amplifier.

Grounding the Comp pin does not inhibit the output. The output may be inhibited by applying >1.2V to the ISENSE pin. 2. This part should be operated with CT=3.3nF and RT=10k timing components only. 1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 321-724-7143 | Intersil (and design) is a registered trademark of Intersil Americas Inc.
