(VDC Typ) Effi ciency (%, Typ) Capacitive Load (µF Max) Fuse Rating Slow-Blow (mA) Voltage (VDC) Current (mA) Voltage (VDC) Current (mA, Max) Current (mA, Min)Nominal Range Full-Load No-Load Notes: 1. Measured with Output 1 at 55% of load while varying output 2 from 10% to 100% load. 2. When measuring output ripple, it’s recommended that an external 4.7 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin for single output units and from each output to common for dual outputs units. 3. These converters are specifi ed for operation without external components. However, in some applications the addition of input/output capacitors will enhance stability and reduce output ripple. Recommended capacitor values are given in the table at right. 4. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 5. Short circuit protection is provided by a “hiccup” mode circuit. 6. These units should not be operated at no-load. A minimum 10% load is recommended for each output. 7. 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.

To adjust the output DOWN, connect a 5%, 3W resistor between the plus output pin and the Vout trim pin. To adjust the output UP , connect a 5%, 3W resistor between the minus utput pin and the Vout trim pin. For UP/Down trimming capability, connect a 10 kW potentiometer between the plus and minus outputs with the wiper arm connected to the Vout trim pin. The trim range is ± 10%. External Trim
