Model Selection Guide

Notes:
1. The specified maximum capacitive load is for each output.
2. Start up time is measured at nominal input and with a constant resistive load.
3. For ±5 and ±9 VOUT models, the output accuracy is specified as ±5%.
4. Cross regulation is measured with the main output set at 50% load. The second output is varied from
10% to 100% load.
5. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 10 µF)
be placed from the +VOUT to the -VOUT pins.
6. Transient recovery is measured to within a 1% error band for a load step change of 25%.
7. Short circuit protection is provided by a “hiccup mode” circuit.
8. The control input (pin 6) is referenced to the -VIN (pin 2) input. If it is grounded, the unit will shut off.
9. Operation at no-load will not damage the unit, but they may not meet all specifications.
10. These units should not be operated over +85°C. Exceeding +85°C may damage the unit.
11. It is recommended that a fuse be used on the input of a power supply for protection. See the Model
Selection table above for the correct rating.

External Trim
External Trim Notes:
On single output units, an external resistor can be used to adjust the converter
output up/down by about 10%. The connection is shown in the diagram at left. The
required resistor value is calculated by the formulas:
Where RTRIM = The value of the external trim resistor
VTRIM = The amount of voltage adjustment required
The value of R1, R2, R3 and VREF are given in the table below.
Trim Down = RTRIM =
R1 - A
A
$ R1 -R

Where A =

VTRIM - VREF $R

Trim UP = RTRIM =
