The VKC03 offers 3 watts of output power from a package in an IC compatible 24pin DIP
configuration without derating to 71ºC ambient temperature. VKC03 series have 4:1 wide
input voltage of 9-36 and 18-75VDC. The VKC03 features 1600VDC of isolation,
short-circuit protection and as well as five sided shielding. A safety designed meet to
EN60950 and UL1950. All models are particularly suited to telecommunications,
industrial, mobile telecom and test equipment applications.

Note
1. The VKC03 series required a minimum 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage
these devices, however they may not meet all listed specification.
2. Simulated source impedance of 12uH. 12uH inductor on series with +Vin.
3. Start up voltage10 Vdc
4. The ON/OFF control pin voltage is referenced to negative input.
5. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
6. M1 version is more efficient, therefore, it can be operated in a more extensive temperature range than standard.
7. Maximum value at nominal input voltage and full load of standard type.
8. Typical value at nominal input voltage and full load
9. Test by minimum Vin and constant resistor load.
