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.
External Trim
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) use:
