DATASHEET
Radiation Hardened High-Speed, Dual Output PWM
HS-1825ARH, HS-1825AEH
The radiation hardened HS-1825ARH, HS-1825AEH 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 radiation hardened Silicon Gate
(RSG) Dielectric Isolation BiCMOS process, the HS-1825ARH,
HS-1825AEH have been specifically designed to provide highly
reliable performance when exposed to harsh radiation
environments.
