AN954: Off-Line Capacitive Power Supply

Manufacturer: Microchip Technology

* From page 10 of AN954:

Figure 10 shows a capacitive power supply with several UL considerations designed in. A fuse is added to protect the circuit during an over-current condition.

Adding R2 in parallel with C1 creates a filter that will attenuate EMI from traveling back onto the line. A varistor, or MOV, provides transient protection.

Advantages of C…
