When measuring output ripple, it is recommended that an external 1.0 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin. 2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 3. The maximum control current at the on/off pin (pin 3) during a logic high is 5 µA. The maximum control current to the on/off pin at logic low is -100 µA. If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut off. 4. Operation at no-load will not damage these units. However, they may not meet all specifi ca- tions. 5. The converter should be connected to a low ac-impedance source. An input source with a highly inductive impedance may affect the stability of the converter. In applications where the converter output loading is high and input power is supplied over long lines, it may be necessary to use a capacitor (such as a low ESR 10.0 µF) on the input to insure start-up. 6. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the correct rating. For continuous UP/Down trimming capability, connect a 10 kW poten- tiometer between the plus and minus outputs with the wiper arm con- nected to the V OUT trim pin. The trim pin may be left fl oating if it is not used. An external resistor may also be used to adjust the converter output. To adjust the output UP , connect a 5%, 3W resistor between the minus output pin and the Vout trim pin. The output voltage is increased per the equation: RUP = (33 x VOUT) - (30 x VADJ) VADJ - VOUT To adjust the output DOWN, connect a 5%, 3W resistor between the plus output pin and the V OUT trim pin. The output voltage is decreased per the equation: RDwn = (36.667 x VADJ) - (33 x VOUT) VOUT - VADJ External Trim Where: VOUT = Nominal Output Voltage VADJ = Adjusted Output Volatage Units = VDC / k Mechanical Dimensions Heatsink Notes:
- Use of the heatsink will extend the units operating temperature range by approximately 10°C.
- The heatsink is black anodized aluminum. MicroPower Direct We Power Your Success - For Less! 292 Page Street Ste D Stoughton, MA 02072 TEL: (781) 344-8226 FAX: (781) 344-8481 E-Mail: sales@micropowerdirect.com Pin Function 1+ V i n 2- V i n
