Data Sheet

September 25, 2008

FN4561.8

Radiation Hardened High-Speed, Dual

Output PWM

Features

• Electrically Screened to DESC SMD # 5962-99558

• QML Qualified per MIL-PRF-38535 Requirements

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.

• Radiation Environment

- Maximum Total Dose . . . . . . . . . . . . . . . . 300 krad(SI)

- Vertical Architecture Provides Low Dose Rate Immunity

- DI RSG Process Provides Latch-Up Immunity

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.

• Low Start-Up Current . . . . . . . . . . . . . . . . . . . 100µA (Typ)

• Fast Propagation Delay . . . . . . . . . . . . . . . . . . 80ns (Typ)

• 12V to 30V Operation

• 1A (Peak) Dual Output Drive Capability

• 5.1V Reference

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.

• Undervoltage Lockout

• Programmable Soft-Start

• Switching Frequencies to 500kHz

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.

• Latched Overcurrent Comparator with Full Cycle Restart

• Programmable Leading Edge Blanking Circuit

Detailed Electrical Specifications for the HS-1825ARH

are contained in SMD 5962-99558. That document may
