Z-ZERIES

28V Input, Single Output

LOW VOLTAGE

HIGH EFFICIENCY

RADIATION HARDENED

DC/DC CONVERTER

Description

The Z-Series of DC/DC converter modules has been

specifically designed in response to the need for low

voltage at moderate current levels supplied with the

high efficiency and tight regulation dictated by modern

digital processing applications. These converters are

designed specifically for operation in radiation environ-

ments that are presented to commercial communica-

tion satellites operating in long term GEO and LEO or-

bits. They have been created to complement the spec-

trum of electrical and radiation performance available

in the Advanced Analog ART2815T and M3G-Series

converters. Requirements occurring in space vehicles

operating in Geostationary orbits, launch boosters, sci-

entific space probes and similar applications requiring

a low voltage, high efficiency converter with well char-

acterized radiation hardness performance will be opti-

mally satisfied by the Z-Series converters.

Features

n Output Voltages from 1.5 to 3.3 Volts

n 20 Amps Output Current

n Synchronous Rectification

n Efficiency up to 88%

n Nominal 28 Volt Input

n Total Ionizing Dose > 100KRad (Si)

n No SEE to LET > 80 MeV^•cm²/mg

n -40°C to +85°C Operating Range

n Short Circuit Protection

n Remote Sensing

n Adjustable Output Voltage

n Flexible Mounting Configuration

n High Power Density

n Derating To MIL-STD-975, MIL-STD-1547,

GSFC-PPL-21

n Fully Isolated - Input to Output and to Case

n Complimentary EMI Filter Available

n Base Plate Conduction Cooling

An additional benefit of the Z-Series is high power den-

sity. This is facilitated by utilizing the best features of

chip and wire hybrid technology and surface mount fab-

rication techniques. The hybrid portion is fabricated in

a facility fully qualified to MIL-PRF-38534 and pro-

cessed to class K requirements. The standard process-

ing adopted for the Z-Series module has been created

to assure with margin the reliability required for space

applications. Applicable generic lot qualification test

data including radiation performance will be made avail-

able on request. Variations to the standard screening

may be accommodated. Consult IR Santa Clara for

special requirements.
