Notes:

1. When measuring output ripple, it is 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 output units.

2. These converters are specified for operation without external components. However, in some

applications the addition of input/ouput capacitors will enhance stability and reduce output

3. Transient recovery is measured to within a 1% error band for a load step change of 75% to

100%.

4. The maximum control current at the on/off pin (pin 6) during a logic high is 50 µA.The maximum

control current to the on/off pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/off pin is left open,

the unit operates. If it is grounded, the unit will shut off.

5. Operation at no-load will not damage these units. However, they may not meet all specifications.

6. Dual output units may be connected to provide a 10 VDC, 24 VDC or 30 VDC output. To do this,

connect the load across the positive (+Vout) and negative (-Vout) outputs and float the output

common.

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.

Remote ON/OFF Notes:

1. Maximum sink current at the on/off pin (pin 6) during a logic

low is 100 µA.

2. Maximum allowable leakage current of a switch connected to

the on/off terminal (Pin 6) at logic high (2.5V to 100V) is 5 µA.

Derating Curve

A simple external circuit may be used to

adjust the converter output (single output

models only). 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%.
