TUMD2

The TUMD2 is designed as one kind of 1.5 W DC/DC converter that provides a cost effective solution in industrial, datacommunication, telecom and medical applications, where ultra high isolation is required. This deviec belongs to the TUMD family that has some points of features:(1)I/O-isolation 6000 VDC; (2)Creeping/ Clearance distances 2.5mm min.; (3)Safety barrier 100% production tested; (4)Meets EN 60950, EN 41003, UL 544 and IEC 601 safety standard (with reinforced insulation for 250 VRMS working voltage); (5)Low leakage current, 2 uA max.; (6)-40 to +85 operating Temperature; (7)24-pin plastic DIP.

The absolute maximum ratings of the TUMD2 can be summarized as:(1)Input current (no load): 50 mA typ. or 30 mA typ.;(2)Input filter: internal filter;(3)Voltage accuracy: ±4 %;(4)Ripple and noise (20 MHz BW): < 50 mVpk-pk;(5)Temperature coefficient: ±0.03 % / °C;(6)Short circuit protection: limited 0.5 sec.;(7)Operating temperature range: -40 °C to +85 °C;(8)Case temperature: +100 °C max.;(9)Storage temperature range: -55 °C to +110 °C;(10)Humidity (non condensing): 95 % rel H max.;(11)Isolation capacity I/O: 10 pF;(12)Isolation resistance I/O (500VDC): > 1'000 MOhm;(13)Soldering temperature: max. 260 °C /10sec..
