D28XXD-SERIES

28V Input, Regulated Dual Outputs

HIGH RELIABILITY,

RADIATION TOLERANT,

LOW POWER,

DC-DC CONVERTER

Description

The D-Series of DC-DC converters are low power

radiation tolerant, high reliability devices designed for

hostile radiation environments such as those

encountered by geostationary earth orbit satellites, deep

space probes and communication systems. Features

include small size, high efficiency, low weight, and a

good tolerance to total ionizing dose, single event

effects, and environmental stresses such as temperature

extremes, mechanical shock, and vibration. All

components are fully derated to meet the requirements

of EEE-INST-002 and MIL-STD-1547B. Extensive

documentation including worst case analysis, radiation

susceptibility, thermal analysis, stress analysis, and

reliability analysis are available.

Features

n Total Dose > 50K Rad(Si)

n SEE > 40MeV.cm²/mg

n Low Weight < 55 grams

n 18V to 50V DC Input Range

n Up to 10W Output Power

n Independently Regulated Outputs:

±5V, ±12V and ±15V

n -55°C to +125°C Operating Temperature Range

n 100MΩ @ 100VDC Isolation

n Input Under-Voltage Protection

n Meets Conducted Emission Requirements

of Most Major Power Buses:

The D-Series converters have two outputs, each is

independently regulated. Two versions exist; One

version providing two positive outputs and one version

providing one negative and one positive output. The D-

Series converters incorporate a fixed frequency flyback

power converter and internal EMI filter that meets the

requirements for most major satellite power buses. The

converters can be remotely turned on and off via an

inhibit pin. Additional inhibit pins are also included to

control the outputs individually. This feature facilitates

turn-on outputs sequencing if desired. Each converter

is encased in a cold rolled steel hermetic package. The

package measures 1.80"L x 1.40"W x 0.42"H and

weighs less than 55 grams. The package utilizes rugged

ceramic feed-through copper pins and is hermetically

sealed using parallel seam welding. Two package

options are available. Please refer to page 9 for I/O

configurations.

100Hz - 100KHz: 80dBµArms

100KHz - 10MHz: Log-linear Decrease

10MHz - 50MHz: 40dBµArms

n Short Circuit and Overload Protection

n Meets the Derating Requirments of

EEE-INST-002 and MIL-STD-1547B

n Synchronization Input / Output

n On/Off Control via Converters’s Inhibit Pin

and Individual Output’s Inhibit Pin

n High CS Damping

Applications

n Launch Vehicles

n Communication Systems

n Geostationary or Low Earth Orbit Satellites

Environmental screening includes temperature cycling,

constant acceleration, fine and gross leak, and burn-in

as specified by MIL-PRF-38534 for class H hybrids.

Non-flight versions of the D-Series converters are

available for system development purposes. Variations

in electrical specifications and screening to meet custom

requirements can be accommodated.
