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.
All specifications are typical at nominal input, full load at 25C unless otherwise stated

Vin = 5.0V, Io = full load, TA = 25C. Total error band 4.5% over all operating conditions and temperatures until end of life. di/dt = 1A/1s, Vin = 5VDC, Tc = 25C, load change = 0.5 lo max. to lo max. and Io max. to 0.5 Io max. With simulated source impedance of 500nH. 5Hz to 20MHz. Use a 100F with ESR = 0.045 max. at 100kHz @ 25C. Referenced to ground for shutdown. If pin 6 is high unit will shut down. If pin 6 is open unit will operate as normal. Single line sense; 0.5VDC compensation. Designate with the suffix 'R' e.g. SIP20C-05S3V3R. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 0-20MHz BW, 0.1F ceramic, 1F tantalum on output. A short from +Vout to ground of less than 100m 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.
Continuous (See Note 9) 6VDC continuous max. UVLO Vin <3.8V Automatic recovery, unit will shut down if RT1 exceeds 85C (See diagram below)
