Radiation Hardened High-Speed, Dual
Output PWM
The Radiation Hardened HS-1825ARH Pulse Width
Modulator is designed to be used in high frequency
switched-mode power supplies and can be used in either
current-mode or voltage-mode. It is well suited for single-
ended boost converter applications.
Device features include a precision voltage reference, low
power start-up circuit, high frequency oscillator, wide-band
error amplifier, and 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.
Constructed with the Intersil Rad Hard Silicon Gate (RSG)
Dielectric Isolation BiCMOS process, the HS-1825ARH has
been specifically designed to provide highly reliable
performance when exposed to harsh radiation
environments.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed below must be used when ordering.
Detailed Electrical Specifications for the HS-1825ARH
are contained in SMD 5962-99558. That document may
be easily downloaded from our website.
