Notes:

1. When measuring output ripple,it is recommended that an external 10.0 µF ceramic capacitor

be placed from the +Vout pin to the -Vout pin. For noise sensitive applications, the use of

47 µF capacitors will reduce the output ripple.

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

100%.

3. The Remote On/Off Control input (Pin 3) is referenced to -Vin (Pin 1). Connection to the

pin should be made through a 1k

resistor and diode (1N4148). If it is not used, the

control pin should be left open.

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

tions.

5. The +sense and -sense connections will compensate for up to 5% of Vout. When not used,

they should be connected directly to the appropriate output pin (+sense to +Vout and -sense

to -Vout).

6. To improve performance and stability, a simple external LC filter can be added to the unit

input.Typical component values would be 1.0 µH/10A & 1,000 µF/25V for 12V input models;

2.2 µH/10A & 1,000 µF/50V for 24V input models; and 74.7 µH/5A & 1,000 µF/100V for 48V

input models.

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.

A simple external circuit may be used to adjust the converter

output. 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 output

pin and the Vout trim pin. To calculate the correct resistor value

(in k

For UP/Down trimming capability, connect a 10 kW potentiometer

between the plus and minus outputs with the wiper arm con-

nected to the Vout trim pin.
