HYBRID - HIGH RELIABILITY

RADIATION HARDENED

DC-DC CONVERTER

Description

The LS-Series of DC-DC converters are, high reliability

devices designed for hostile radiation hardened

environments. The LS-Series provide up to 30 watts

output power, small size, low weight, integrated EMI

filtering and a high tolerance to environmental stresses

such as radiation, temperature extremes, mechanical

shock, and vibration. Extensive documentation

including, thermal analysis, stress analysis and reliability

predictions are available.

The LS-Series of converters incorporate a fixed

frequency single forward topology with magnetic

feedback and an internal EMI filter. These converters

are capable of meeting the conducted emissions

requirements of MIL-STD-461C without any additional

components. All models include an external inhibit port

and have an adjustable output voltage. They are

enclosed in a hermetic 1.5" x 2.3" x 0.425" steel package

and weigh less than 80 grams. The package utilizes

rugged ceramic feed-through copper core pins and is

sealed using parallel seam welding.

The LS-Series of DC-DC converters provide same

mechanical outline, power ratings, for backward pin

compatibility, to their lower radiation tolerant counterpart

M3L and Military series ATS DC-DC converters. The

common platform design allows for similarity between

military and space system architectures. For higher

output power applications the HM, M3H and M3G-Series

of DC-DC converters are recommended.

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.

Variations in electrical specifications and screening to

meet custom requirements can be accommodated.
