15W - Single Output - Wide Input - Isolated & Regulated
1“ x 1“ DC-DC Converter
Input Reflected Ripple Current Test Setup
Output Ripple and Noise Test Setup
Measure input reflected ripple current with a simulated
source inductance of 12µH. The measurement points for
input reflected ripple current is showed above.
Scope measurements should be made using a BNC
socket, with a 1µF ceramic capacitor and a 10 µF tantalum
capacitor. Position the oscilloscope probe between 51mm
and 76mm (2 inch and 3 inch) from the module.
Remote on/off
The REM pin is used to turn the power converter remote on
or off via a system signal. This power module is negative logic
version. When the REM pin is at logic high the power turns off
and turns on at logic low.
To turn the power module on and off, the user must supply a
switch to control the voltage between the REM pin and -Vin
terminal (see Figure 3). A logic low is VREM = -0.7V to 0.8V.
The maximum IREM during logic low is 1mA. The switch
should maintain a logic low voltage while sinking 1mA. During
logic high, the typical maximum VREM voltage is18V.
If not using the remote on/off feature, short REM pin to -Vin.

Application of trim and calculation of trim resistance
3.3V
12V
Output voltage trim allows the user to increase or decrease
the output voltage set point of a module. This is
accomplished by connecting an external resistor between the
TRIM pin and either the Vout+ or Vout- pins. If not using the
trim feature, leave the TRIM pin open.
