SMT20C

Embedded Power for Business-Critical Continuity SMT20C Series 5 Vin and 12 Vin single output Rev.06.25.07 SMT20C 1 of 4 Total Power: 66W Input Voltage: 4.5-5.5 Vdc # of Outputs: Single Special Features • 20 A current rating • Input voltage range: 4.5 Vdc - 5.5 Vdc or 10.2 Vdc - 13.8 Vdc • Output voltage range: 0.9 Vdc - 3.3/5.0 Vdc • Industry leading value • Cost optimized design • Excellent transient response • Output voltage adjustability • Pathway for future upgrades • Supports silicon voltage migration • Resulting in reduced design-in and qualification time • Designed in reliability: MTBF of >7 million hours per Telcordia SR-332 • Available RoHS compliant • 2 year warranty The SMT20C Series is a new high density open frame non-isolated converter for space-sensitive applications. Each model has a wide input range (4.5 Vdc to 5.5 Vdc or 10.2 Vdc to 13.8 Vdc) and offers a wide 0.9 Vdc to 3.3/5 V output voltage range with a 20 A load. An external resistor adjusts the output voltage from its pre-set value of 0.9 V to any value up to the maximum allowed value for that model. Typical efficiencies are 87% for the 5 V input version and 91% for the 12 V input version at full load conditions. The SMT20C series offers remote ON/OFF and overcurrent protection as standard. With full international safety approval including EN60950 and UL/cUL60950, the SMT20C reduces compliance costs and time to market Safety UL/cUL CAN/CSA 22.2 No. 60950 UL 60950 File No. E139421 TÜV Product Service (EN60950:2000) Certificate No. B 04 08 19870 228 CB report and certificate to US/6415C/UL Embedded Power for Business-Critical Continuity Specifications All specifications are typical at nominal input Vin=12V, full load at 25°C unless otherwise stated.
