GH-SERIES

28V Input, Single Output

HIGH RELIABILITY, HIGH EFFICIENCY

RADIATION HARDENED

DC-DC CONVERTER

Description

The GH series is a family of low voltage single output

DC-DC converters. They are specifically designed in

response to the need for low voltage at moderate current

levels with the high efficiency and tight regulation

Features

dictated by modern digital processing applications. The

converters are radiation hardened, high reliability

converters designed for extended operation in hostile

environments. Their small size and low weight make

them ideal for applications such as geostationary earth

orbit satellites and deep space probes. They exhibit a

high tolerance to total ionizing dose, single event effects

and environmental stresses such as temperature

extremes, mechanical shock, and vibration. All

components are fully de-rated to meet the requirements

of MIL-STD-975, MIL-STD-1547 except for the CDR type

of capacitors, a capacitor with 50V rating is used for in-

circuit voltage stress of less than10V. Thorough analyses

and documentation including beginning-of-life (BOL)

and end-of-life (EOL) electrical worst case (WCA)

operation, component stress and de-rating, radiation

susceptibility (TREE), thermal stress, failure mode and

effects (FMEA), and reliability (MTBF) are available for

customer review.

n High Efficiency - to 87%

n -55°C to +85°C Operating Temperature Range

n 100MΩ @ 100VDC Isolation

n Under-Voltage Lockout

n Short Circuit and Overload Protection

n Output Voltage Adjust

n Synchronization Output and Input

n External Inhibit

The design incorporates a fixed frequency topology

with magnetic feedback. Synchronous rectification is

deployed to maximize efficiency performance. The

converters include an internal EMI filter that is capable

of meeting the conducted emission requirements of

most major satellite power busses. Incorporation of

many functional features including on/off command,

remote sensing, and under-voltage lockout make the

design suitable for today’s space design applications.

Applications

Deep Space Satellites / Probes

Strategic Weapons and Communication System

Geostationary Earth Orbit Satellites (GEO)

Manufactured in a facility fully qualified to MIL-

PRF-38534, these converters are fabricated

utilizing DLA Land and Maritime qualified

processes. For available screening options, refer

to device screening table in the data sheet.

The converter is enclosed in a hermetically sealed

package with the overall dimensions of 3.5"L x 2.50”W

x 0.475"H including the I/O pins and mounting tabs.

The package base material is silicon carbide-

aluminum (AISIC). The package ring frame is Alloy

48. The package utilizes rugged ceramic feed-through

copper core I/O pins and is sealed using parallel

seam welding. The total mass of a converter is less

than 110 grams.

Non-flight versions of the GH-Series converters

are available for system development purposes.

Variations in electrical specifications and

screening to meet custom requirements can be

accommodated.
