The new SN6501 transformer driver in combination with the new center-tap transformers from Wuerth-Electronics/Midcom allows for ultra low-cost isolated DC-DC converter designs with very small form factors. This apps-note show two circuits with unregulated and regulated outputs and their measured performance characteristics for a wide range of transformers from Wuerth-Electronics/Midcom, Coilcraft, and Murata.
For detailed information consult the SN6501 data sheet and its extensive application section.
Kind regards, Thomas
In combination with the new low-saturation transformers from Wuerth, even the unregulated output voltage shows a fairly flat characteristic so that in most cases an LDO is not required and the circuits performas well with just two 1uF ceramic capacitors. TK
Hi,
i am working on an application design that requires an isolated dc dc converter with specs of 5V/5V and an output current of 10mA max. what would be the input current at Vin=5V in the circuit given in Figure 2 of the apps-note? and also what is the quiescent current of this circuit at no load?
Regards,
Hur
