Hi-Rel DC/DC CONVERTER MGDM-20 : 20W POWER Hi-Rel Grade Single, Bi & Triple Outputs Metallic Case - 1.500 VDC Isolation • 28Vdc input compliant with MIL-STD-704 D/E • Nominal power up to 20 W www.DataSheet4U.com • Wide temperature range : -40°C/+105°C case • High efficiency (typ. 84%) • Soft start • Galvanic isolation 1.500 VDC • Integrated LC EMI filter • Permanent short circuit protection • No optocoupler for high reliability 1-General The MGDM-20 series is a complete line of high performance DC/DC power modules designed for aerospace, military and high-end industrial applications. These modules use a high frequency fixed swiching technic at 500KHz providing excellent reliability, low noise characteristics and high power density. Standard models are available with standard input voltage range of 4.5-5.5, 9-36 and 16-40 volts. The series include single bi and triple output voltage choices of 3,3 , 5, 12, 15 volts. No external heatsink is required for the MGDM20 series to supply 20W 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, and a permanent short circuit protection to ensure efficient module protection. 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 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 with a GAIA converter automated test equipment.The modules are potted with a bi-component thermal conductive compound and packaged in a metallic case to ensure the module’s integrity under high environmental conditions. 4 2-Product Selection Single output model Bi output model Triple output model : MGDS-20: MGDB-20: MGDT-20(/T) and/or (/S) (/T) and/or (/S) (/T) and/or (/S) (/T) : option for -55°C start up operating temperature (/S) : option for screening and serialization Input Voltage Range Permanent C : 4,5-5,5 VDC H : 9-36 VDC J : 16-40 VDC Transient n/a 40 VDC/100 ms* 50 VDC/100 ms* Output B : 3.3 VDC C : 5 VDC or +/-5VDC E : 12 VDC or +/-12VDC F : 15 VDC or +/-15VDC BE : 3,3 VDC and +/-12 VDC BF : 3,3 VDC and +/-15 VDC CE : 5 VDC and +/-12 VDC CF : 5 VDC and +/-15 VDC * Consult factory for details REDEFINING THE SOURCE OF POWER © Gaia Converter FC98-016.08/04 Revision I For locations, phone, fax, E-Mail see back cover MGDM-20 Series 2- Product Selection (continued) Input range 4,5-5,5 4,5-5,5 4,5-5,5 4,5-5,5 9-36 9-36 9-36 9-36 9-36 9-36 9-36 9-36 9-36 9-36 9-36 16-40 16-40 16-40 16-40 16-40 16-40 16-40 16-40 16-40 16-40 16-40 VDC VDC VDC VDC Output 3,3 VDC 5 VDC 12 VDC 15 VDC 3,3 VDC 5 VDC 12 VDC 15 VDC +/- 5 VDC +/- 12 VDC +/- 15 VDC 3,3 & +/- 12 VDC 3,3 & +/- 15 VDC 5 & +/- 12 VDC 5 & +/- 15 VDC 3,3 VDC 5 VDC 12 VDC 15 VDC +/- 5 VDC +/- 12 VDC +/- 15 VDC 3,3 & +/- 12 VDC 3,3 & +/- 15 VDC 5 & +/- 12 VDC 5 & +/- 15 VDC Current 4A 4A 1,6 A 1,3 A 4A 4A 1,6 A 1,3 A +/- 2A +/- 0,8 A +/- 0,65 A A & +/- 0,4 A & +/- 0,3 A & +/- 0,4 A & +/- 0,3 4A 4A 1,6 A 1,3 A +/- 2A +/- 0,8 A +/- 0,65 A A & +/- 0,4 A & +/- 0,3 A & +/- 0,4 A & +/- 0,3 Reference MGDS-20-C-B MGDS-20-C-C MGDS-20-C-E MGDS-20-C-F MGDS-20-H-B MGDS-20-H-C MGDS-20-H-E MGDS-20-H-F MGDB-20-H-C MGDB-20-H-E MGDB-20-H-F MGDT-20-H-BE MGDT-20-H-BF MGDT-20-H-CE MGDT-20-H-CF MGDS-20-J-B MGDS-20-J-C MGDS-20-J-E MGDS-20-J-F MGDB-20-J-C MGDB-20-J-E MGDB-20-J-F MGDT-20-J-BE MGDT-20-J-BF MGDT-20-J-CE MGDT-20-J-CF Hi-Rel Grade Options /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T /T , , , , , , , , , , , , , , , , , , , , , , , , , , /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S /S www.DataSheet4U.com VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC VDC 2 2 2 2 A A A A 2 2 2 2 A A A A 4 Converter Selection Chart MGDS - 20 - H - C / T Number of Outputs : S : single output B : bi ouput T : triple output Input voltage range : C : 4,5-5,5 VDC H : 9-36 VDC J : 16-40 VDC Output voltage : See table page 1 Option : /T : -55°C start up operation /S : screening and serialization (consult application note «screening grades») © Gaia Converter FC98-016.08/04 Revision I 2 For locations, phone, fax, E-Mail see back cover MGDM-20 Series 3- Electrical Specifications Data are valid at +25°C, unless otherwise specified.
