1-General

The TETHYS 30W series is a full family of highly

configurable DC/DC low profile power module

designed for direct implementation on high

density printed circuit boards designed for

aerospace, military and high-end industrial ap-

plications. This module uses a high frequency

fixed swiching technic at 480 KHz providing ex-

cellent reliability, low noise characteristics and

low profile package. This model is available with

nominal input voltages as 12 or 28 volts in range

of 9-36 or 16-40 volts. The serie includes

thousands of output configuration from single,

bi up to six possible output voltages in choices

of 3,3, 5, 12, 15, 24 volts with trim and sense

functions for output voltage adjustment.

No external heatsink is required for the for CGDM

series to supply 30W output power over the

case temperature range of -40°C up to 105°C.

All the modules are designed with LC network

filters to minimize reflected input current ripple

and output voltage ripple.

The modules include undervoltage lock-out, a

permanent short circuit protection an output

overvoltage protection and a thermal protection

to ensure efficient module protections.

The soft-start allows current limitation and

eliminates inrush current during start-up. The

short circuit protection completely protects the

module against short-circuits of any duration by

a shut-down and restores to normal when the

overload is removed. The thermal protection is

adjusted to 110°C and protects the module

against overheat.

The inhibit function is commanded with a low

logic level and disables the module for applica-

tions requiring on/off operations.

The design has been carried out with surface

mount components and is manufactured in a

fully automated process to guarantee high

quality. Each module is tested and burned-in

with a GAIA Converter automated test

equipment.

Note * : For proper operation the CGDI module requires to install a 22µF chemical or tantalum capacitance accross output terminals.

Note ** : For 9-36V inpt range, the power is derated at 80% at 9V and increases linearly to full power at 12V.

Note*** : The ripple output voltage is the periodic AC component imposed on the output voltage, an aperiodic and random component (noise) has also to be considered. This noise can

be reduced by adding an external capacitor (typically 10nF/rated voltage depending on isolation requirement) connected between the pin Gin and the pin Gout of the converter. This capacitor

should be layed-out as close as possible from the converter.

Note **** : For load regulation characteristics from 0% to full load, please contact factory.
