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 specified 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.

For heatsink option, add suffix “H” to model number (i.e. B2003ERW-H)

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%.
