SIP20C Series Single output DC-DC CONVERTERS • • • • • • • • • • 9-20 W Non-isolated DC-DC Regulators 1 Updated version of SIP20 Best-of-class wide output trim range Industry standard footprint High power density (60 W/in3) High Efficiency 90% Fixed frequency (500 kHz) Remote ON/OFF Undervoltage lockout (UVLO) Remote sense option Available RoHS compliant The SIP20C series are non-isolated dc-dc converters packaged in a single-in-line footprint (2.5 x 0.55 x 0.23 inches) giving designers a cost effective solution for conversion of 5 Vdc to 3.3 Vdc and lower voltages. The SIP20C offers a best-of-class wide output trim range which allows maximum design flexibility and a pathway for future upgrades. Local voltage conversion by the SIP20C from existing 5 V system voltages eliminates the need for redesign of existing power architectures when voltage requirements change. The SIP20C is designed for applications that include distributed power, workstations, computers and file servers. Implementing state of the art surface mount technology and automated manufacturing techniques, the SIP20C offers compact size and efficiencies of 90%. The SIP20C is an updated version of the original SIP20 and is fully compatible with the original model. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input, full load at 25 °C unless otherwise stated OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Voltage adjustability S3V3J S2V5J S1V5J Set point accuracy (See Note 1) ±2.7% Line regulation Vin = 4.5-5.5 V ±0.3% Load regulation Io = 0-6 A ±0.3% Minimum load 0A Overshoot/undershoot Ripple and noise (See Note 8) None 0 to 20 MHz BW Temperature coefficient 100 mV pk-pk, 30 mV rms max.

If pin 6 is high unit will shut down. If pin 6 is open unit will operate as normal. 6 Single line sense; 0.5 Vdc compensation. Designate with the suffix 'R' e.g. SIP20C-05S3V3RJ. 7 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 8 0 MHz to 20 MHz BW, 0.1 µF ceramic, 1 µF tantalum on output. 9 A short from +Vout to ground of less than 100 mΩ may cause the unit to enter a non-destructive latch-up mode. If latch-up does occur the power supply to the unit may need to be cycled. 10 The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details. 11 NOTICE: Some models do not support all options.
