1-General

The TETHYS 30W wide input series is a full family

of highly configurable DC/DC low profile mo-

dule designed for use in distributed power ar-

chitecture where variable input voltage and

transient are prevalent and are particularly

suitable for mobile application in transportation,

or high-end industrial areas. This module uses

a high frequency fixed swiching technic at

480KHz providing excellent reliability, low noise

characteristics and low profile package. Stan-

dard models are available with wide input vol-

tage range of 4.7-16, 9-36, 16-40 or 36-140

volts. The serie includes thousands of output

configuration from single, bi up to six ouput

voltages in choice of 3,3, 5, 12, 15, 24 volts

with trim and sense functions for output vol-

tage adjustment.

No external heatsink is required for the CGDI

series to supply 30W output power over the full

temperature range.

All the modules are designed with LC network

filters to minimize reflected input current ripple

and output voltage ripple.

The modules include a soft-start, an input

undervoltage lock-out, a permanent short cir-

cuit 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 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.
