SIL/SMT20C2 Series 4.5 Vin to 13.8 V Single Output DC-DC CONVERTERS • • • • • • • • • August 27, 2008 1 C Class Non-isolated 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 NEW Product 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. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input, full load at 25 °C, unless otherwise stated GENERAL SPECIFICATIONS OUTPUT SPECIFICATIONS Output voltage (See Note 5) Output setpoint accuracy 0.1% trim resistors Line regulation Low line to high line Load regulation Full load to min. load Min/max load Efficiency Vin=5 V, Vo=2.5 V, lo=20 A ±1.0% Switching frequency Fixed ±0.2% Approvals and standards (pending) 0.59-5.1 V ±0.5% 0 A/20 A Overshoot At turn-on 0.5% max.

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. Notes 1 2 3 4 5 6 7 8 9 Measured as per recommended system capacitance. di/dt = 10 A/μs, Vin = Nom, Tc = 25 °C, load change = 0.75 lo to full lo and full lo to 0.75. External input fusing is recommended. Additional part numbers may be available with different output voltages. Airflow dependent, 100 LFM minimum required. No capacitor needed for ripple current capability. No capacitor needed for stability.
