SIL/SMT20C2 Series 4.5 Vin to 13.8 V Single Output August 27, 2008 DC-DC CONVERTERS C Class Non-isolated 1 20 A current rating NEW Product 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/ 2 YEAR WARRANTY OFF and over-current protection as standard. All specifications are typical at nominal input, full load at 25 C, unless otherwise stated SPECIFICATIONS GENERAL SPECIFICATIONS OUTPUT SPECIFICATIONS Output voltage (See Note 5) 0.59-5.1 V Efficiency Vin=5 V, Vo=2.5 V, lo=20 A 90% Output setpoint 0.1% trim resistors 1.0% Switching frequency Fixed 750 kHz accuracy Approvals and EN60950 standards (pending) UL/cUL6950 Line regulation Low line to high line 0.2% Load regulation Full load to min. load 0.5% Material flammability UL94V-0 Weight 8.50 g/0.3 oz.

It is no longer necessary to purchase a variety of modules in order to cover different output voltages. The output voltage can be trimmed in a range of 0.59-5.1 V. When the SIL/SMT20C2 converter leaves the factory, the ouput has been adjusted to the default voltage of 0.59 V.
