DESCRIPTION
The JF series of DC/DC power converters provides 15 Watts of output power in a low profile industry standard package and footprint.
These converters have single outputs and operate over 2:1 input voltage ranges of 18-36VDC and 36-75VDC. These units are also
protected against short circuit, over current, over voltage, and input under voltage conditions. Some features include high efficiency up
to 88%, adjustable output voltage, and positive or negative remote ON/OFF control. These converters are RoHS compliant and have
UL60950-1, EN60950-1, and IEC60950-1 safety approvals. Both surface mount (“S” suffix) and DIP (standard) packages are available.

NOTES
1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC.
MIL-HDBK-217F
Notice2 @ Ta=25°C, Full load (Ground, benign, controlled environment).
2. Maximum value at nominal input voltage and full load.
3. Typical value at nominal input voltage and no load.
4. Typical value at nominal input voltage and full load.
5. Test by minimum input and constant resistive load.
6. Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an
external resistor between the TRIM pin and either the +OUTPUT pin or the –OUTPUT pin.
7. The CTRL pin voltage is referenced to -INPUT. (See the “Product Options” table on page 5 for suffix options).
8. The power module can operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure
reliable operation.
9. The JF Series meets EN55022 Class A and Class B only with external components connected to the input pins of the converter.
10. An external filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5. The filter capacitor suggested is
Nippon chemi-con
KY Series, 220μF/100V, ESR 48mΩ.
11. This product is Listed to applicable standards and requirements by UL.
CAUTION:
These power modules are not internally fused. An input line fuse must always be used.
*Due to advances in technology, specifications subject to change without notice.
OUTPUT ADJUSTABILITY
Output voltage adjustment 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 +OUTPUT or -OUTPUT pins. With an external resistor between the
TRIM and -OUTPUT pin, the output voltage set point increases. With an external resistor between the TRIM and +OUTPUT pin, the
output voltage set point decreases. The external TRIM resistor needs to be at least 1/16W.
