All parameters NOT specially mentioned are measured at 12, 48VDC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 5. For the input line, a 47uF/100V electrolytic capacitor with Esr<1 is used in the test. 6.EMC filter suggestion(TBD): 5.5uH + Vin - + 680uF + PSU Vo - File Name:NSD05-S-SPEC 2008-01-30 NSD05-S 5W DC-DC Regulated Single Output Mechanical Specification series Unit:mm[inch] 40.6 [1.6] 30.48 [1.2] 4 2 22.86[0.9] 5 2.54[0.1] 10.16[0.4] 15.24[0.6] 25.4[1] 2.54[0.1] 10.16 [0.4] 1 8.3 [0.327] 6 [0.236] 3 [0.118] 1.5[0.059] 3 0.64mm square pins Pin No. Assignment Pin No. 1 2 3 Assignment +INPUT -INPUT(GND) +VOUT Pin No. 4 5 Assignment -VOUT CONTROL Block Diagram fosc : 350KHz POWER SWITCHING I/P O.L.P.
