The SMT12F features an ‘Active Low’ Remote ON/OFF operation. If you are not using the Remote ON/OFF pin, leave the pin open (the converter will be on). The Remote ON/OFF pin is The ultra-wide output voltage trim range offers major advantages to users referenced to ground. The following conditions apply for the SMT12F: who select the SMT12F. It is no longer necessary to purchase a variety of modules in order to cover different output voltages. The output voltage can be Configuration Converter Operation Remote pin open circuit Unit is ON trimmed in a range of 0.9 Vdc to 2.6 Vdc or 0.9 Vdc to 3.3 Vdc. When the Remot pin pulled low Unit is ON SMT12F-05W3V3J converter leaves the factory the output has been adjusted Remote pin pulled high Unit is OFF to the default voltage of 3.3 V. When the SMT12F-03W2V6J converter leaves the factory the output has been adjusted to the default voltage of 2.6 V. A ‘Active High’ Remote ON/OFF version is also possible with this converter. To order please place the suffix ‘-R’ at the end of the model number, e.g. SMT12F-05W3V3RJ. 2. See Figures 1 and 2 for sample derating curves.

See Performance Application Note 165 for further details. < 4.5 Vdc 0.9 - 2.0 Vdc 05W3V3J 4. An external output capacitor is required for basic operation. Required capacitance is a minimum of 110 μF to meet the performance parameters. This can be made up of any combination of 22 μF or 44 μF multi-layer ceramic capacitors in the appropriate voltage rating. 5. Ripple and Noise is worst case measurement. Typical value is 26 mV pk-pk. 6. NOTICE: Some models do not support all options.
