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

Use a 100 µF with ESR = 0.045 Ω max. at 100 kHz @ 25 °C.
5
Referenced to ground for shutdown. 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

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.
