Model and electrical selection

Model and package MDD01M-15N; 1 W isolated unregulated converter in a SIP 7 package. S denotes single output, D denotes dual output; the final N identifies the catalog N series.
DC input range 10.8–13.2 V DC; nominal 12 V DC (±10% input range).
Input current 18 mA at no load; 114 mA at full load.
Output voltage ±15 V DC; positive and negative rails relative to Common.
Output current range 4–34 mA per output rail. Maintain the specified minimum load on each rail.
Rated output power 1 W total rated output. Observe this power limit together with the stated voltage and current limits.
Efficiency 80% typical.
Capacitive load 100 µF maximum for each output.
Input filter and fuse Internal capacitor input filter; a 500 mA slow-blow input fuse is recommended.
Voltage accuracy and regulation Voltage accuracy: ±5.0%. Line regulation: 1.2% for a 1% input variation, measured from low line to high line at rated load.
Load regulation ±10%, measured from 10% to 100% rated load.
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 30 kHz typical.

Protection and medical isolation

Short-circuit protection Continuous short-circuit protection with automatic recovery.
Isolation and patient leakage Reinforced primary-to-secondary isolation: 1 × MOPP / 2 × MOOP at a system input of 250 V AC. Patient leakage is specified as 2 µA maximum at 250 V AC, 50/60 Hz; the feature summary describes low leakage below 2 µA.
Withstand voltage Input to output: 6 kV DC.

Isolation capacitance 10 pF typical.
Safety approvals IEC62368-1 / UL62368-1, LVD IEC60601-1 and EAC TP TC 020/2011 approved as stated in the module datasheet. Compliance of the complete medical equipment remains a system-level requirement.

EMC and circuit integration

EMC emissions Conducted and radiated emissions: BS EN/EN55032 and BS EN/EN55011, Class A/B with the specified external components. Reconfirm EMC compliance in the final equipment.
EMC suggestion circuit The catalog's typical recommended Class A/B circuit uses an LDM series inductor of 47 µH and input capacitor C1 of 10 µF. A 470 pF / 6 kV DC capacitor connects the module-side +Vin node to output Common. Follow the exact 12 V input circuit on PDF page 4; the C1 voltage rating is not specified and must be selected for the application.
