SIP20C Series Single output DC/DC CONVERTERS • • • • • • • • • 9-20W Non-isolated DC/DC Regulators 1 Updated version of SIP20 Best-of-class wide output trim range Industry standard footprint High power density (60W/in3) High Efficiency 90% Fixed frequency (500kHz) Remote ON/OFF Undervoltage lockout (UVLO) Remote sense option 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 5VDC to 3.3VDC 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. For example, the 1.5V model can be trimmed as low as 1V. Local voltage conversion by the SIP20C from existing 5V 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 S3V3 S2V5 S1V5 Set point accuracy (See Note 1) ±2.7% Line regulation Vin = 4.5V to 5.5V ±0.3% Load regulation Io = 0A to 6A ±0.3% Minimum load 0A Overshoot/undershoot Ripple and noise (See Note 8) None 0 to 20MHz BW Temperature coefficient 100mV pk-pk, 30mV rms max.
