Industrial DC/DC CONVERTER MGDDI-06 Ultra Wide Input : 6W POWER Industrial Grade 12:1 Ultra Wide Input Dual Outputs Metallic Case - 2 250 VDC Isolation • Ultra wide input range • Nominal power up to 6 W • Nominal dual output voltage from 5V to 48V • High efficiency over the entire range • Soft start • Galvanic isolation 2 250 VDC • Integrated LC input filter • Permanent short circuit protection • External trim adjustment : -20/+10% • No optocoupler for high reliability • RoHS process 1-General The MGDDI-06 ultra wide input series designates a full family of DC/DC power modules designed for use in distributed power architecture where variable input voltage for multiple battery and transient are prevalent making them ideal particularly for transportation/mass transit, railways or high-end industrial applications. These modules use a fixed frequency switching topology providing excellent reliability, low noise characteristics and very high efficiency over the entire input voltage range. Standard models are available with a permanent ultra wide input voltage range of 12-160 volts fully compatible with 24V/36V/72V/110V/125V battery applications. The serie includes dual output voltage choices individually isolated of 2 x 5 volts , 2 x 12 volts, 2 x 15 volts and 2 x 24 volts with easy configurability. The MGDDI-06 serie is designed in compliance with safety standards EN60950. All the modules are designed with LC network filters to minimize reflected input current ripple according to ease EN55022 standard. The modules include a soft-start, an input undervoltage lock-out, a permanent short circuit protection and an output overvoltage limitation 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 modules against short-circuits of any duration by a shut-down and restores to normal operation when the overload is removed. 2-Product Selection Dual output model : MGDDI - 06 - input output Input Voltage Range Permanent R : 12-16O VDC Output C E F I : : : : 2 x 5 VDC 2 x 12 VDC 2 x 15 VDC 2 x 24 VDC REDEFINING THE SOURCE OF POWER © Gaia Converter FC16-079.06/22 Revision G For locations, phone, fax, E-Mail see back cover 5 Industrial Grade MGDDI-06 Ultra Wide Input Series 2- Product Selection (continued) Input range 12-160 12-160 12-160 12-160 VDC VDC VDC VDC Output Current per Output Reference Options 2 x 5 VDC 2 x 12 VDC 2 x 15 VDC 2 x 24 VDC 0,60 A 0,25 A 0,20 A 0,125 A MGDDI-06-R-C MGDDI-06-R-E MGDDI-06-R-F MGDDI-06-R-I / / / / / Using various parallel or series connections of outputs, and the 80/110% trim capability, allows to cover almost the complete range of output voltages from 4V to 52V as shown in the table below.

To calculate the maximum admissible ambient temperature the following method can be used. Heat can be removed from the baseplate via three basic mechanisms : Knowing the power used Pout and the efficiency η: • determine the power dissipated by the module Pdiss that should be evacuated : η - 1) (A) Pdiss = Pout(1/η • Radiation transfert : radiation is counting for less than 5% of total heat transfert in majority of case, for this reason the presence of radient cooling is used as a safety margin and is not considered. • Conduction transfert : in most of the applications, heat will be conducted from the baseplate into an attached heatsink or heat conducting member; heat is conducted thru the interface. • Convection transfert : convecting heat t r a n s f e r into air refers to still air or forced air cooling. In majority of the applications, we will consider that heat will be removed from the baseplate either with : • heatsink, • forced air cooling, • both heatsink and forced air cooling. • then determine the thermal dissipation : Tdiss = Rth(b-a) x Pdiss (B) where Rth(b-a) is the thermal resistance from the baseplate to ambient. This thermal Rth(b-a) resistance is the summ of : • the thermal resistance of baseplate to heatsink (Rth(b-h)). The interface between baseplate and heatsink can be nothing or a conducting member, a thermal compound, a thermal pad.... The value of Rth(b-h) can range from 0.4°C/W for no interface down to 0.1°C/W for a thermal conductive member interface. • the thermal resistance of heatsink to ambient air (Rth(h-a)), which is depending of air flow and given by heatsink supplier. 5 The table hereafter gives some example of thermal resistance for different heat transfert configurations.

On Off Without resistor, the turn on voltage is 11.8V and turn off voltage is 10.8V UVLO Turn- off UVLO Turn- on UVLO Turn- off UVLO Turn- on Vin Uvlo Voltage trimming 150 Turn on voltage turn off voltage 130 110 Vuvlo (Vdc) The UVLO voltage can be adjusted using a resistor (Ruvlo) connected between pin 2 and Gi. This value can be ajusted in order to allow converter to stops properly accordingly to the input bus (or battery ) voltage value. The Ruvlo can be determined using the following formula : Ruvlo (KΩ) = [200.3-Vuvlo]/[Vuvlo-11.8] Ruvlo = trimming resistance Vuvlo = desire turn-on voltage 90 70 50 30 10 100 1000 Ruvlo (Ω) 10000 100000 12-2 Output Over Current Limitation Protection (OCP) The MGDDI-06 Series incorporates a overcurrent protection circuit. The overcurrent protection detects short circuit or over curent and protects the module according to the hiccup graph . The maximum detection current Id is depending on input voltage Vin, temperature, and is higher than 105 % maximum nominal output curent. When OCP is triggered, the converter falls in hiccup mode by testing periodically if the overload is still present. The module restart automatically to normal operation when overcurrent is removed. Td (detection time) and Th (hiccup period) are depending on Vin and temperature. In hiccup mode the average curent is arround 25 % of Inom. © Gaia Converter 5 9 FC16-079.06/22 Revision G For locations, phone, fax, E-Mail see back cover MGDDI-06 Ultra Wide Input Series Industrial Grade 13- Description of Functions 13-1 Connection of Outputs The outputs of MGDDI-06 can be connected in various configurations such as : - connections in series - connection in parallel - connection in symmetry - connection in independance Please note that regulation is achieved through output V01/G01 referenced as primary output. When connected in symetrie or independant configurations with unbalanced loads, VO1/GO1 has to be loaded at 0,5W minimum to insure proper operating of the converter. The V02/G02 output referenced as secondary output may stay unloaded, but in that case its regulation may drift up as shown in curve below. There is no minimum load when the two outputs are connected in parallel or balanced serie. 13-1-1 Connection of Outputs in Series 13-1-2 Connection of Outputs in Parallel Outputs connected in series allow to achieve 10V, 24V, 30V or 48V output voltages up to 6W total power. These values can be extended using trim adjustment. Outputs connected in paralell allow to achieve single output 5V, 12V, 15V or 24V up to 6W power. These values can be extended using trim adjustment. 5 13-1-3 Connection of Outputs in Symmetry Outputs connected in symetrie allow to achieve +/-5V, +/-12V, +/-15V or +/-24V voltages (+/-3W each) with possible unbalanced loadup to 5W on primary outout, 1W on secondary output and vice versa. 13-1-4 Connection of Outputs in Independance Outputs connected independantly with floating DC between each other can be achieved for 2x5V, 2x12V, 2x15V or 2x24V voltages (3W each) with possible unbalanced load up to 5W on primary output 1W on secondary output and vice versa. © Gaia Converter 10 FC16-079.06/22 Revision G For locations, phone, fax, E-Mail see back cover MGDDI-06 Ultra Wide Input Series Industrial Grade 13- Description of Functions (continued) 13-2 Trim Function The output voltage Vo1 may be trimmed in a range of 80%/110% of the nominal output voltage (100%/110% for 3,3 Vdc output voltage) via a single external trimpot or fixed resistor. The VO2 output will be automatically trimmed in the same value than VO1, whatever the outputs combination is. Trim Up Function Do not attempt to trim the module higher than 110% of nominal output voltage as the overvoltage protection may occur. Also do not exceed the maximum rated output power when the module is trimmed up. The trim up resistance must be calculated with the following formula : Ru is trim resistor value in KOhm VOnom is nominal output voltage VO is desired trimmed output voltage Trim Down Function Do not trim down more than -20% of nominal output voltage otherwise the module may be damaged. 5 The available output power is reduced by the same percentage that output voltage is trimmed down. The trim down resistance must be calculated with the following formula : Rd is trim resistor value in KOhm VOnom is nominal output voltage VO is desired trimmed output voltage © Gaia Converter 11 FC16-079.06/22 Revision G For locations, phone, fax, E-Mail see back cover MGDDI-06 Ultra Wide Input Series Industrial Grade 13- Description of Functions (continued) 13-3 On/Off Function The control pin 1 (On/Off) can be used for applications requiring On/Off operation. This may be done with an open collector transistor, a switch, a relay or an optocoupler. Several converters may be disabled with a single switch by connecting all On/Off pins together. • The converter is disabled by pulling low the pin 1. • No connection or high impedance on pin 1 enables the converter.

It is recommended to provide for at least 10uF/low ESR ceramic capacitors. These capacitors should have the proper voltage rating and should be connected between «VIF» and «Gin» as close as possible from the converter, using large copper traces. © Gaia Converter 5 12 FC16-079.06/22 Revision G For locations, phone, fax, E-Mail see back cover MGDDI-06 Ultra Wide Input Series Industrial Grade 14- Dimensions 2 mm (+/- 0.01 “) unless3 otherwise indicated. 4 Dimension are given 1in mm.
