My customer was considering using TPS7A78 for their AC to DC power supply. But the requirement of output current is changed up to 300mA. But output current limitation of TAP7A78 is up to 120mA.
Is there any solution to meet customer request? Main concern point of customer is solution size.
The customer can accept Discrete Capacitor drop regulator. Is it available up to 0.3A output current using cap-drop regulator?
- input : 100 ~ 240VAC (50/60Hz)
- output : 3.3V / 300mA
- non isolated and transformer-less type
Please let me know your opinion regarding minimum solution to meet customer concept.
