1 / 4 page SIL/SMT20C2 Series 4.5 Vin to 13.8 V Single Output File Name: sil/smt20c2.pdf Rev: 27 Aug 2008 August 27, 2008 2 YEAR WARRANTY • 20 A current rating • Input voltage range: 4.5-13.8 V • Output voltage: 0.59-5.1 V • Industry leading value • Cost optimized design • Excellent transient response • Output enable • Output voltage adjustability • Pathway for future upgrades • Supports silicon voltage migration • Resulting in reduced design-in and qual time • Current sink capability • RoHS compliant The SIL/SMT20C2 series is a new high density, open frame, non-isolated converter for space sensitive applications. This model has a wide input range (4.5-13.8 Vdc) and offers a wide 0.59-5.1 V output voltage range with 20 A load capability. An external resistor adjusts the output voltage from its pre-set value of 0.59 V to any value up to the 5 V maximum. Typical efficiencies for the models are 93% for the 12 V input version. The series offers remote ON/ OFF and over-current protection as standard.
