Edition

Description

The IMX15, IMS15, and IMY15 Series of board mountable 15-

Watt DC-DC converters have been designed according to the

latest industry requirements and standards. The converters

are particularly suitable for use in mobile or stationary

applications in transport, railways, industry, or telecommu-

nications, where variable input voltages or high transient

voltages are prevalent.

Covering a total input voltage range from 8.4 up to 150 V with

different models, the converters are available with single and

electrically-isolated double outputs from 3.3 up to 48 V,

externally adjustable, with flexible load distribution on double-

output models. A shutdown input allows for remote on/off.

Features include efficient input and output filtering and

consistently high efficiency over the entire input voltage range,

high reliability, and excellent dynamic response to load and

line changes.

The converters have been approved by CSA. 20IMS/20IMX15

and 40IMS/40IMX15 models provide supplementary in-

sulation. Connected to a secondary circuit, these models

provide SELV outputs, even if the bus voltage at the converter

110IMY15

models

input exceeds the SELV-limit of 60 VDC. The 110IMY15

models provide double insulation and are CE marked. They

may be connected to a rectified 110 VAC source without any

further isolation barrier.

The circuitry is comprised of integrated planar magnetics. All

components are automatically assembled and solidly soldered

onto a single PCB without any wire connection. Magnetic

feedback ensures maximum reliability and repeatability in the

control loop over all operating conditions. Careful con-

sideration of possible thermal stress ensures the absence of

hot spots providing long life in environments, where

temperature cycles are frequent. The thermal design allows

operation at full load up to an ambient temperature of 71 °C in

free air without using any potting material. For extremely high

vibration environments the case has holes for screw mounting.

IMX15, IMS15, IMY15 Series Data Sheet

15 -Watt DC-DC Converters

RoHS- Compliant Models

The type designation of RoHS-compliant models (compliant for the restriction of all six substances) for the IMX/IMY15 Series

ends with "G".

However, in single-output models with 3.3 V or 5.1 V output an extra hyphen (-) is added after the existing "G", which already

signifies a synchronous rectifier. This is an exception to Power-One's normal nomenclature to identify this type of product, since

G is already used to designate products for higher output current fitted with a synchronous rectifier. As an example

– 20IMX15-05-8R-G means a standard version with RoHS compliance for all six substances.

– 20IMX15-05-8RG means a synchronous rectifier version which is not RoHS-compliant.

– 20IMX15-05-8RG-G means a synchronous rectifier version and with RoHS compliance for all six substances.

– 20IMX15-05-05-8RG means a double-output model with RoHS compliance for all six substances

– 110IMY15-24-24-8RG means a double-output model with RoHS compliance for all six substances.
