dc/dc converters 9-20w non-isolated dc/dc regulators 1 2 year warranty sip20c series single output ? updated version of sip20 ? best-of-class wide output trim range ? industry standard footprint ? high power density (60w/in 3 ) ? 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. local voltage conversion by the sip20c from existing 5v system voltages eliminates the need for r edesign 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 emc characteristics (4) radiated emissions en55022/11, fcc part 15 level a electrostatic discharge en61000-4-2, iec801-2 general specifications efficiency see table isolation voltage non-isolated switching frequency fixed 500khz typ. approvals and vde0805, en60950, iec950 standards (see note 7) ul1950, csa c22.2 no. 950 material flammability ul94v-0 dimensions (lxwxh) 63.5 x 13.97 x 5.84 mm 2.5 x 0.55 x 0.23 inches pin length 0.135 0.02 inches (3.43 0.5mm) w eight 5g (0.18oz) mtbf mil-hdbk-217f >1,000,000 hours environmental specifications thermal performance operating ambient, see curve convection cooled operating ambient, -25c to +85c 300lfm forced air see curve non-operating -55c to +100c altitude operating 10,000 feet max. non-operating 40,000 feet max. v ibration 5hz to 500hz 2.4g rms (approx.) output specifications v oltage adjustability s3v3 60% to 115% s2v5 60% to 110% s1v5 87% to 130% 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 none ripple and noise 0 to 20mhz bw 100mv pk-pk, (see note 8) 30mv rms max. t emperature coefficient 0.01%/c t ransient response 2.0% max. deviation (see note 2) 300s recovery to within 1.0% remote sense (see note 6) 0.5vdc compensation input specifications input voltage range 4.5 to 5.5vdc input current no load 150ma input current @ io max. and 5.3a max. v in = 0 to 5.5v input reflected ripple (see note 3) 200ma remote on/off (see note 5) start-up time 1.0ms external capacitor (see note 4) 100f specifications international safety standard approvals vde0805/en60950/iec950 pending ul1950 csa 22.2 no. 950 pending file name: sip20c.pdf rev: 05 feb 2003
