Model and electrical selection

Model and package MDD06G-15; 6 W isolated regulated medical DC/DC converter in a DIP 24 package with standard pinout. S denotes single output and D denotes dual output.
DC input range 18–75 V DC, 4:1 range; listed nominal inputs 24 / 48 V DC.
Input current 15 mA at no load; 310 mA at full load.
Output voltage ±15 V DC; positive and negative rails relative to Common.
Output current range 20–200 mA per output rail. Maintain the specified minimum load on each rail.
Rated output power 6 W total rated output; observe the stated voltage and current limits.
Efficiency 82% typical.
Capacitive load 47 µF maximum for each output.
Input surge, filter and fuse 100 V DC input surge for 100 ms maximum. Pi-type input filter. Typical input-protection recommendation: 1 A slow-blow fuse.
Voltage accuracy and line regulation Voltage accuracy: ±2%. Line regulation: ±0.5%, measured from low line to high line at rated load.
Load regulation ±0.5%, measured from 10% to 100% rated load for MDD06.
Ripple and noise 100 mVp-p. Measured with a 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Switching frequency 280 kHz typical.

Protection and medical isolation

Short circuit and overload Continuous short-circuit protection with automatic recovery. Overload: 110–250% of rated output power, recovering automatically after the fault is removed.
Undervoltage lockout Start-up voltage: 8.8 V DC; shutdown voltage: 8 V DC, as listed in the common specification table.
Isolation and patient leakage Reinforced primary-to-secondary isolation: 2 × MOPP when the system input is 250 V AC, 50/60 Hz. The catalog specifies low patient leakage below 5 µA.
Withstand voltage Input to output: 6 kV DC or 4.2 kV AC.
Isolation resistance and capacitance Isolation resistance: 1,000 MΩ at 500 V DC, 25°C and 70% RH. Isolation capacitance: 20 pF typical.
Safety approvals IEC60601-1 (LVD), 3rd edition, and EAC TP TC 020/2011 approved. The catalog limits EAC TP TC 004 to the 48 V input type. Complete medical-equipment compliance must be assessed at system level.

EMC and circuit integration

EMC emissions BS EN/EN55011 conducted-emission entry: N/A. Radiated emissions: Class A without external EMC components; Class B requires the specified external circuit. Reconfirm final-equipment EMC.
EMC suggestion circuit The Class B suggestion circuit on PDF page 21 shows C1 and C2 each 4.7 µF / 100 V MLCC, L1 = 450 µH common-mode choke; C3 and C4 are marked X (not fitted). The diagram names both MDS06 and MDD06, but the component-table row is labeled MDS06G; confirm its applicability to this dual-output model with MEAN WELL before implementing it.
EMC immunity BS EN/EN61000-4-2: ±15 kV air; -4-3: 10 V/m; -4-4: ±2 kV; -4-5: ±2 kV line to line; -4-6: 10 Vrms (e.m.f.); -4-8: 30 A/m.

Thermal, environmental and assembly limits

Operating temperature and derating −40 to +90°C with free-air convection. The natural-convection curve shows full load through +71°C, 75% at +80°C and 50% at +90°C. The plot beyond +90°C does not extend the specified operating range.
Case temperature and humidity Case temperature: +105°C maximum. Working humidity: 20–90% RH, non-condensing.
Storage −55 to +125°C; 10–95% RH, non-condensing.
Temperature coefficient 0.05%/°C over 0–71°C.
Soldering At 1.5 mm from the case: 3–5 seconds, 265°C maximum.
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, for 60 minutes along each X, Y and Z axis.

Mechanical layout and pin assignment

Dimensions and case 31.8 × 20.3 × 12.2 mm (L × W × H); UL94V-0 plastic case.
Mechanical tolerances General x.x / x.xx dimensions: ±0.5 mm. Pin size: 0.6 ±0.10 mm; lead extension: 3.81 mm.
PCB footprint Top-view PCB layout: Ø0.8 mm holes (+0.2 / −0); 2.54 mm grid and 15.24 mm pin-row spacing. The body drawing gives a 2.06 mm end offset and a 5.08 mm span between pins 10 and 12 / pins 15 and 13. Verify orientation using the bottom-view module and top-view PCB drawings on PDF page 20.
Pin assignment Pin 1: +Vin; pin 10: no pin; pin 11: Common; pin 12: no pin; pin 13: −Vout; pin 15: +Vout; pins 23 and 24: −Vin.

Test conditions, packing and applications

Specification test conditions Unless otherwise stated: 24 V DC normal input for the G model, rated load, 25°C and 70% RH ambient.
MTBF Greater than 454 kh, MIL-HDBK-217F at 25°C.
Unit weight 17 g catalog packing reference per unit; not a separately measured net weight.
Bulk packing 15 units per tube, 750 units in 50 tubes maximum per carton. One tube gross weight: 310 g; carton gross weight: 16.1 kg. Carton: 620 × 230 × 230 mm. The packing illustration shows a 520 mm tube length and a 24 × 21.3 mm outer cross-section.
