| (1/2) DC to DC Converters Non-insulation Type, Wide Input, SMD CE-1050 Series FEATURES * Wide input voltage range (DC.12 to 24V). * A thickness dimension is a low height of 54.5mm. * It is available in the wide temperature range from -20 to +85C. * Equipped with ON/OFF control feature * Available with a wide-range +3.3 to +12.6V output voltage variation feature * Equipped with overcurrent protection feature * Due to the shielding structure of five-side in metal, this series feature low EMI. * SMD type is available for feeding with both tray and taping. * It is a product conforming to RoHS directive. SPECIFICATIONS AND STANDARDS Part No. Input voltage range Output current range1 Output voltage setting range2 Output voltage total variation3 Oscillating frequency Output ripple noise voltage4 Efficiency5 V A V % kHz mVp-p % ON V ON/OFF control voltage OFF V Overcurrent protection A 1 Input/output potential difference must be at least 4V. 2 When output voltage is set at 12V, it is 5% max. 3 When output voltage is set at 12V, it is 100mV max. 4 With 18V input voltage, 5V output voltage, 2.5A output current. 5 Derating may occur depending upon the output voltage.

Conformity to RoHS Directive OUTPUT VOLTAGE SETTING METHOD By connecting a Rex external resistor, output voltage can be altered. It is not necessary to attach a Rex when using at a 5V output voltage. * To raise the output voltage: insert the Rex between pin 7 and 8 Rex = 13.31-Vout Vout-5 Unit: V, k 1 Vin 0.1F 2 3 4 OFF ON 5 10 9 8 7 6 0.1F Load Load Rex COMMON SPECIFICATIONS Operating temperature range Storage temperature range Humidity range -20 to +85C -20 to +85C 10 to 90(%)RH * To lower the output voltage: insert the Rex between pin 8 and 9 Rex = 7.8xVout-13.31 5-Vout Unit: V, k PRECAUTIONS * Since this product uses a multilayered board, it has moistureproof packaging.After opening, if the injector value is 30% or more, defects such as pattern breaking may occur during reflow, so be sure to perform baking procedures (JEDEC MSL level 3). Recommended baking conditions: once at 120C, 120minutes * This product cannot be cleaned. Use low-residue or non-cleaning type flux and refrain from cleaning. * The packaging type of this product is solely taping packaging. Packaging amount is 400 items/reel. 1 Vin 0.1F 2 3 4 OFF ON 5 10 9 8 7 6 Rex 0.1F Output can be started and stopped by controlling terminal 5. Since this termina is pulled up via a 2A internal current source, by connecting a condenser, the start up time can be delayed. The delay time is approximately 0.3ms per 1000pF. * Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications. * All specifications are subject to change without notice. 001-02 / 20060214 / ea381_ce_1050.fm (2/2) SHAPES AND DIMENSIONS 1.50.2 1.40.2 RECOMMENDED PC BOARD PATTERN[TOP VIEW] 1.4 1.0 18.3 (22.7) 5.5max.
