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.

NOTES:
1. Index area: A notch or a pin one identification mark shall be locat-
ed adjacent to pin one and shall be located within the shaded
area shown. The manufacturer’s identification shall not be used
as a pin one identification mark.
2. The maximum limits of lead dimensions b and c or M shall be
measured at the centroid of the finished lead surfaces, when
solder dip or tin plate lead finish is applied.
3. Dimensions b1 and c1 apply to lead base metal only. Dimension
M applies to lead plating and finish thickness.
4. Corner leads (1, N, N/2, and N/2+1) may be configured with a
partial lead paddle. For this configuration dimension b3 replaces
dimension b2.
5. Dimension Q shall be measured from the seating plane to the
base plane.
6. Measure dimension S1 at all four corners.
7. Measure dimension S2 from the top of the ceramic body to the
nearest metallization or lead.
8. N is the maximum number of terminal positions.
9. Braze fillets shall be concave.
10. Dimensioning and tolerancing per ANSI Y14.5M - 1982.
11. Controlling dimension: INCH.
