Hi-Rel DC/DC CONVERTER MGDM-10 : 10W POWER Hi-Rel Grade Single, Bi & Triple Outputs Metallic Case - 1.500 VDC Isolation • 28Vdc input compliant with MIL-STD-704 D/E • Low profile : 0,33 “ (8.5mm) • Nominal power of 10 W without derating • Wide temperature range : -40°C/+105°C case • High efficiency up to 83 % • Soft start 1-General • Galvanic isolation 1.500 VDC • Integrated LC EMI filter • Permanent short circuit protection • Parallel operation master/slave • No optocoupler for high reliability The MGDM-10 series is a full family of high performance DC/DC low profile power modules designed for aerospace, military and high-end industrial applications. These modules use a high frequency fixed switching technic at 480 KHz providing excellent reliability, low noise characteristics, high power density and a low profile package. Standard models are available with nominal input voltages as 5, 12 or 28 volts in range of 4,5-5,5 9-36 or 1640 volts. The series include single bi and triple output voltage choices of 3,3, 5, 12, 15, +/-5, +/ -12, +/-15 or +/-24 volts. No external heatsink is required for the MGDM-10 series to supply 10W 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. 2-Product Selection The modules include a soft-start, an input undervoltage lock-out, a permanent short circuit protection and an output overvoltage 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 shutdown and restores to normal when the overload is removed. 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 before and after encapsulation.The modules are potted with an excellent thermal conductive compound and packaged in a metallic case to ensure the module’s integrity under high temperature conditions.

The maximum ambient temperature admissible for the DC/DC converter corresponding to the maximum operating case temperature of 105°C depends on the ambient airflow, the mounting/orientation, the cooling features and the power dissipated. To calculate a maximum admissible ambient temperature the following method can be used. Knowing the maximum case temparature Tcase = 105°C of the module, the power used Pout and the efficiency η : • determine the power dissipated by the module Pdiss that should be evacuated : η - 1) Pdiss = Pout(1/η • determine the maximum ambient temperature : Ta = 105°C - Rth x Pdiss where Rth is the thermal resistance from the case to ambient. 4 The previous thermal calculation shows two areas of operation : • a normal operation area in a free natural ambient convection (grey area in this following graph), • an area with cooling features (air flow or heatsink) ensuring a maximum case temperature below the maximum operating case temperature of 105°C (white area in the following graph).

There is no hysteresis cycle at turn-on and turn-off. On Off UVLO Turn-on/Turn-off Vin 11-2 Output Short Circuit Protection (SCP) The short circuit protection device protects the module against short circuit of any duration and restores the module to normal operation when the short circuit is removed. It operates in «hiccup» mode by testing periodically if an overload is applied (typically every 200ms recovery time). The overload detection threshold is typically 200% of maximum current with a detection time lower than 5ms. Vo (%) 100 detection time x time recovery time recovery time 11-3 Output Overvoltage Protection (OVP) 4 The output overvoltage protection device protects external components against high voltage or possible overvoltages which can be supplied by the module (i.e in case of internal failure). It consists of a zener diode clamping the output voltage; under worst case conditions this zener diode will short-circuit. The output voltage protection is not designed to withstand externally applied output overvoltages to protect the module itself. 12- Description of Functions 12-1 Option (/M) : On/Off Function The optionnal control pin A (On/Off) can be used for applications requiring On/Off operation. By using an open collector command with a transistor Q referenced to the common terminal (Gi) : • A logic pulled low (<0.2V@1mA, referenced to Gi) on pin A disables the converter • No connection or high impedance on pin A enables the converter. On/Off Command By releasing the On/Off function, the converter will restart within the start-up time specifications given in table page 3. For further details please consult ‘’Logic On/Off’’ Application Note. © Gaia Converter FC97-010.08/08 Revision P GI 11 For locations, phone, fax, E-Mail see back cover MGDM-10 Series Hi-Rel Grade 13- Application Notes 13-1 Connection of Outputs in Series Any of the bi output converters can be configured to produce an output of 10V (+/-5 output models), 24V (+/-12V output models), or 30V (+/-15V output models) by connecting the load across the output (+) and the output (-) with either output grounded, and leaving the common pin floating. VI +Vo Go GI -Vo VI Vo 2 x Vo 13-2 Connection of Modules in Series The output of single output units can be connected in series without any precautions to provide higher output voltage level. Nevertheless, GAIA Converter recommends to protect each individual output by a low power shottky diode rated with the maximum current of the converter to avoid reverse polarity at any output. Reverse polarity may occur at start up if the output voltages do not rise at the same time. Gate GI Go VI Vo 2 x Vo 4 Gate GI Go 13-3 Connection of Modules in Parallel The MGDM-10 series feature a current share function. Several converters with equal output voltage can be connected in parallel to increase power. A «master» module will synchronize a «slave» module to the same clock allowing a current share in between modules through the «gate» pin. A master module MGDS-10 can drive up to 2 slave modules MGDE-10 .
